Example:
# The code below shows an example of how to instantiate this type. # The values are placeholders you should change. from aws_cdk import aws_route53 as route53 cfn_record_set_group = route53.CfnRecordSetGroup(self, "MyCfnRecordSetGroup", comment="comment", hosted_zone_id="hostedZoneId", hosted_zone_name="hostedZoneName", record_sets=[route53.CfnRecordSetGroup.RecordSetProperty( name="name", type="type", # the properties below are optional alias_target=route53.CfnRecordSetGroup.AliasTargetProperty( dns_name="dnsName", hosted_zone_id="hostedZoneId", # the properties below are optional evaluate_target_health=False ), cidr_routing_config=route53.CfnRecordSetGroup.CidrRoutingConfigProperty( collection_id="collectionId", location_name="locationName" ), failover="failover", geo_location=route53.CfnRecordSetGroup.GeoLocationProperty( continent_code="continentCode", country_code="countryCode", subdivision_code="subdivisionCode" ), geo_proximity_location=route53.CfnRecordSetGroup.GeoProximityLocationProperty( aws_region="awsRegion", bias=123, coordinates=route53.CfnRecordSetGroup.CoordinatesProperty( latitude="latitude", longitude="longitude" ), local_zone_group="localZoneGroup" ), health_check_id="healthCheckId", hosted_zone_id="hostedZoneId", hosted_zone_name="hostedZoneName", multi_value_answer=False, region="region", resource_records=["resourceRecords"], set_identifier="setIdentifier", ttl="ttl", weight=123 )] )
- Parameters:
scope (
Construct
) – Scope in which this resource is defined.id (
str
) – Construct identifier for this resource (unique in its scope).comment (
Optional
[str
]) – Optional: Any comments you want to include about a change batch request.hosted_zone_id (
Optional
[str
]) – The ID of the hosted zone that you want to create records in. Specify eitherHostedZoneName
orHostedZoneId
, but not both. If you have multiple hosted zones with the same domain name, you must specify the hosted zone usingHostedZoneId
.hosted_zone_name (
Optional
[str
]) – The name of the hosted zone that you want to create records in. You must include a trailing dot (for example,www.example.com.
) as part of theHostedZoneName
. When you create a stack using anAWS::Route53::RecordSet
that specifiesHostedZoneName
, AWS CloudFormation attempts to find a hosted zone whose name matches theHostedZoneName
. If AWS CloudFormation can’t find a hosted zone with a matching domain name, or if there is more than one hosted zone with the specified domain name, AWS CloudFormation will not create the stack. Specify eitherHostedZoneName

element for each record that you want to create.
Methods
- add_deletion_override(path)
Syntactic sugar for
addOverride(path, undefined)
.- Parameters:
path (
str
) – The path of the value to delete.- Return type:
None
- add_dependency(target)
Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.
- Parameters:
target (
CfnResource
) –- Return type:
None
- add_depends_on(target)
(deprecated) Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
- Parameters:
target (
CfnResource
) –- Deprecated:
use addDependency
- Stability:
deprecated
- Return type:
None
- add_metadata(key, value)
Add a value to the CloudFormation Resource Metadata.
- Parameters:
key (
str
) –value (
Any
) –
- See:
- Return type:
None
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.
- add_override(path, value)
Adds an override to the synthesized CloudFormation resource.
To add a property override, either use
addPropertyOverride
or prefixpath
with “Properties.” (i.e.Properties.TopicName
).If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.
To include a literal
.
in the property name, prefix with a\
. In most programming languages you will need to write this as"\\."
because the\
itself will need to be escaped.For example:
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"]) cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")
would add the overrides Example:
"Properties": { "GlobalSecondaryIndexes": [ { "Projection": { "NonKeyAttributes": [ "myattribute" ] ... } ... }, { "ProjectionType": "INCLUDE" ... }, ] ... }
The
value
argument toaddOverride
will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.- Parameters:
path (
str
) –The path of the property, you can use dot notation to override values in complex types. Any intermediate keys will be created as needed.
value (
Any
) –The value. Could be primitive or complex.
- Return type:
None
- add_property_deletion_override(property_path)
Adds an override that deletes the value of a property from the resource definition.
- Parameters:
property_path (
str
) – The path to the property.- Return type:
None
- add_property_override(property_path, value)
Adds an override to a resource property.
Syntactic sugar for
addOverride("Properties.<...>", value)
.- Parameters:
property_path (
str
) – The path of the property.value (
Any
) – The value.
- Return type:
None
- apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)
Sets the deletion policy of the resource based on the removal policy specified.
The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.
The resource can be deleted (
RemovalPolicy.DESTROY
), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN
). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT
). A list of resources that support this policy can be found in the following link:- Parameters:
policy (
Optional
[RemovalPolicy
]) –apply_to_update_replace_policy (
Optional
[bool
]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: truedefault (
Optional
[RemovalPolicy
]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resource, please consult that specific resource’s documentation.
- See:
- Return type:
None
- get_att(attribute_name, type_hint=None)
Returns a token for an runtime attribute of this resource.
Ideally, use generated attribute accessors (e.g.
resource.arn
), but this can be used for future compatibility in case there is no generated attribute.- Parameters:

- hosted_zone_id
The ID of the hosted zone that you want to create records in.
- hosted_zone_name
The name of the hosted zone that you want to create records in.
- logical_id
The logical ID for this CloudFormation stack element.
The logical ID of the element is calculated from the path of the resource node in the construct tree.

RecordSet
element for each record that you want to create.
- ref
Return a string that will be resolved to a CloudFormation

Lazy.any({ produce: resource.ref })
.
- stack
The stack in which this element is defined.
CfnElements must be defined within a stack scope (directly or indirectly).
Static Methods
- classmethod is_cfn_element(x)
Returns
true
if a construct is a stack element (i.e. part of the synthesized cloudformation template).Uses duck-typing instead of
instanceof
to allow stack elements from different versions of this library to be included in the same stack.- Parameters:
x (
Any
) –- Return type:
bool
- Returns:
The construct as a stack element or undefined if it is not a stack element.
- classmethod is_cfn_resource(x)
Check whether the given object is a CfnResource.
- Parameters:
x (
Any
) –- Return type:
bool
- classmethod is_construct(x)
Checks if
x
is a construct.Use this method instead of
instanceof
to properly detectConstruct
instances, even when the construct library is symlinked.Explanation: in JavaScript, multiple copies of the
constructs
library on disk are seen as independent, completely different libraries. As a consequence, the classConstruct
in each copy of theconstructs
library is seen as a different class, and an instance of one class will not test asinstanceof
the other class.npm install
will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of theconstructs
library can be accidentally installed, andinstanceof
will behave unpredictably. It is safest to avoid usinginstanceof
, and using this type-testing method instead.- Parameters:
x (
Any
) – Any object.- Return type:
bool
- Returns:
true if
x
is an object created from a class which extendsConstruct
.
AliasTargetProperty
- class CfnRecordSetGroup.AliasTargetProperty(*, dns_name, hosted_zone_id, evaluate_target_health=None)
Bases:
object
Alias records only: Information about the AWS resource, such as a CloudFront distribution or an Amazon S3 bucket, that you want to route traffic to.
When creating records for a private hosted zone, note the following:
Creating geolocation alias and latency alias records in a private hosted zone is allowed but not supported.
For information about creating failover records in a private hosted zone, see Configuring Failover in a Private Hosted Zone .
- Parameters:
dns_name (
str
) –Alias records only: The value that you specify depends on where you want to route queries:. - Amazon API Gateway custom regional APIs and edge-optimized APIs - Specify the applicable domain name for your API. You can get the applicable value using the AWS CLI command get-domain-names : - For regional APIs, specify the value of
regionalDomainName
. - For edge-optimized APIs, specify the value ofdistributionDomainName
. This is the name of the associated CloudFront distribution, such asda1b2c3d4e5.cloudfront.net
. .. epigraph:: The name of the record that you’re creating must match a custom domain name for your API, such asapi.example.com
. - Amazon Virtual Private Cloud interface VPC endpoint - Enter the API endpoint for the interface endpoint, such asvpce-123456789abcdef01-example-us-east-1a.elasticloadbalancing.us-east-1.vpce.amazonaws.com
. For edge-optimized APIs, this is the domain name for the corresponding CloudFront distribution. You can get the value ofDnsName
using the AWS CLI command describe-vpc-endpoints . - CloudFront distribution - Specify the domain name that CloudFront assigned when you created your distribution. Your CloudFront distribution must include an alternate domain name that matches the name of the record. For example, if the name of the record is acme.example.com , your CloudFront distribution must include acme.example.com as one of the alternate domain names. For more information, see Using Alternate Domain Names (CNAMEs) in the Amazon CloudFront Developer Guide . You can’t create a record in a private hosted zone to route traffic to a CloudFront distribution. .. epigraph:: For failover alias records, you can’t specify a CloudFront distribution for both the primary and secondary records. A distribution must include an alternate domain name that matches the name of the record. However, the primary and secondary records have the same name, and you can’t include the same alternate domain name in more than one distribution. - Elastic Beanstalk environment - If the domain name for your Elastic Beanstalk environment includes the region that you deployed the environment in, you can create an alias record that routes traffic to the environment. For example, the domain namemy-environment. *us-west-2* .elasticbeanstalk.com
is a regionalized domain name. .. epigraph:: For environments that were created before early 2016, the domain name doesn’t include the region. To route traffic to these environments, you must create a CNAME record instead of an alias record. Note that you can’t create a CNAME record for the root domain name. For example, if your domain name is example.com, you can create a record that routes traffic for acme.example.com to your Elastic Beanstalk environment, but you can’t create a record that routes traffic for example.com to your Elastic Beanstalk environment. For Elastic Beanstalk environments that have regionalized subdomains, specify theCNAME
attribute for the environment. You can use the following methods to get the value of the CNAME attribute: - AWS Management Console : For information about how to get the value by using the console, see Using Custom Domains with AWS Elastic Beanstalk in the AWS Elastic Beanstalk Developer Guide . - Elastic Beanstalk API : Use theDescribeEnvironments
action to get the value of theCNAME
attribute. For more information, see DescribeEnvironments in the AWS Elastic Beanstalk API Reference . - AWS CLI : Use thedescribe-environments
command to get the value of theCNAME
attribute. For more information, see describe-environments in the AWS CLI . - ELB load balancer - Specify the DNS name that is associated with the load balancer. Get the DNS name by using the AWS Management Console , the ELB API, or the AWS CLI . - AWS Management Console : Go to the EC2 page, choose Load Balancers in the navigation pane, choose the load balancer, choose the Description tab, and get the value of the DNS name field. If you’re routing traffic to a Classic Load Balancer, get the value that begins with dualstack . If you’re routing traffic to another type of load balancer, get the value that applies to the record type, A or AAAA. - Elastic Load Balancing API : UseDescribeLoadBalancers
to get the value ofDNSName
. For more information, see the applicable guide: - Classic Load Balancers: DescribeLoadBalancers - Application and Network Load Balancers: DescribeLoadBalancers - CloudFormation Fn::GetAtt intrinsic function : Use the Fn::GetAtt intrinsic function to get the value ofDNSName
: - Classic Load Balancers . - Application and Network Load Balancers . - AWS CLI : Usedescribe-load-balancers
to get the value ofDNSName
. For more information, see the applicable guide: - Classic Load Balancers: describe-load-balancers - Application and Network Load Balancers: describe-load-balancers - Global Accelerator accelerator - Specify the DNS name for your accelerator: - Global Accelerator API : To get the DNS name, use DescribeAccelerator . - AWS CLI : To get the DNS name, use describe-accelerator . - Amazon S3 bucket that is configured as a static website - Specify the domain name of the Amazon S3 website endpoint that you created the bucket in, for example,s3-website.us-east-2.amazonaws.com
. For more information about valid values, see the table Amazon S3 Website Endpoints in the Amazon Web Services General Reference . For more information about using S3 buckets for websites, see Getting Started with Amazon Route 53 in the Amazon Route 53 Developer Guide. - Another Route 53 record - Specify the value of theName
element for a record in the current hosted zone. .. epigraph:: If you’re creating an alias record that has the same name as the hosted zone (known as the zone apex), you can’t specify the domain name for a record for which the value ofType
isCNAME
. This is because the alias record must have the same type as the record that you’re routing traffic to, and creating a CNAME record for the zone apex isn’t supported even for an alias record.hosted_zone_id (
str
) –Alias resource records sets only : The value used depends on where you want to route traffic:. - Amazon API Gateway custom regional APIs and edge-optimized APIs - Specify the hosted zone ID for your API. You can get the applicable value using the AWS CLI command get-domain-names : - For regional APIs, specify the value of
regionalHostedZoneId
. - For edge-optimized APIs, specify the value ofdistributionHostedZoneId
. - Amazon Virtual Private Cloud interface VPC endpoint - Specify the hosted zone ID for your interface endpoint. You can get the value ofHostedZoneId
using the AWS CLI command describe-vpc-endpoints . - CloudFront distribution - SpecifyZ2FDTNDATAQYW2
. This is always the hosted zone ID when you create an alias record that routes traffic to a CloudFront distribution. .. epigraph:: Alias records for CloudFront can’t be created in a private zone. - Elastic Beanstalk environment - Specify the hosted zone ID for the region that you created the environment in. The environment must have a regionalized subdomain. For a list of regions and the corresponding hosted zone IDs, see AWS Elastic Beanstalk endpoints and quotas in the Amazon Web Services General Reference . - ELB load balancer - Specify the value of the hosted zone ID for the load balancer. Use the following methods to get the hosted zone ID: - Service Endpoints table in the “Elastic Load Balancing endpoints and quotas” topic in the Amazon Web Services General Reference : Use the value that corresponds with the region that you created your load balancer in. Note that there are separate columns for Application and Classic Load Balancers and for Network Load Balancers. - AWS Management Console : Go to the Amazon EC2 page, choose Load Balancers in the navigation pane, select the load balancer, and get the value of the Hosted zone field on the Description tab. - Elastic Load Balancing API : UseDescribeLoadBalancers
to get the applicable value. For more information, see the applicable guide: - Classic Load Balancers: Use DescribeLoadBalancers to get the value ofCanonicalHostedZoneNameID
. - Application and Network Load Balancers: Use DescribeLoadBalancers to get the value ofCanonicalHostedZoneID
. - CloudFormation Fn::GetAtt intrinsic function : Use the Fn::GetAtt intrinsic function to get the applicable value: - Classic Load Balancers: Get CanonicalHostedZoneNameID . - Application and Network Load Balancers: Get CanonicalHostedZoneID . - AWS CLI : Usedescribe-load-balancers
to get the applicable value. For more information, see the applicable guide: - Classic Load Balancers: Use describe-load-balancers to get the value ofCanonicalHostedZoneNameID
. - Application and Network Load Balancers: Use describe-load-balancers to get the value ofCanonicalHostedZoneID
. - Global Accelerator accelerator - SpecifyZ2BJ6XQ5FK7U4H
. - An Amazon S3 bucket configured as a static website - Specify the hosted zone ID for the region that you created the bucket in. For more information about valid values, see the table Amazon S3 Website Endpoints in the Amazon Web Services General Reference . - Another Route 53 record in your hosted zone - Specify the hosted zone ID of your hosted zone. (An alias record can’t reference a record in a different hosted zone.)evaluate_target_health (
Union
[bool
,IResolvable
,None
]) – Applies only to alias records with any routing policy: WhenEvaluateTargetHealth
istrue
, an alias record inherits the health of the referenced AWS resource, such as an ELB load balancer or another record in the hosted zone. Note the following: - CloudFront distributions - You can’t setEvaluateTargetHealth
totrue
when the alias target is a CloudFront distribution. - Elastic Beanstalk environments that have regionalized subdomains - If you specify an Elastic Beanstalk environment inDNSName
and the environment contains an ELB load balancer, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. (An environment automatically contains an ELB load balancer if it includes more than one Amazon EC2 instance.) If you setEvaluateTargetHealth
totrue
and either no Amazon EC2 instances are healthy or the load balancer itself is unhealthy, Route 53 routes queries to other available resources that are healthy, if any. If the environment contains a single Amazon EC2 instance, there are no special requirements. - ELB load balancers - Health checking behavior depends on the type of load balancer: - Classic Load Balancers : If you specify an ELB Classic Load Balancer inDNSName
, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. If you setEvaluateTargetHealth
totrue
and either no EC2 instances are healthy or the load balancer itself is unhealthy, Route 53 routes queries to other resources. - Application and Network Load Balancers : If you specify an ELB Application or Network Load Balancer and you setEvaluateTargetHealth
totrue
, Route 53 routes queries to the load balancer based on the health of the target groups that are associated with the load balancer: - For an Application or Network Load Balancer to be considered healthy, every target group that contains targets must contain at least one healthy target. If any target group contains only unhealthy targets, the load balancer is considered unhealthy, and Route 53 routes queries to other resources. - A target group that has no registered targets is considered unhealthy. .. epigraph:: When you create a load balancer, you configure settings for Elastic Load Balancing health checks; they’re not Route 53 health checks, but they perform a similar function. Do not create Route 53 health checks for the EC2 instances that you register with an ELB load balancer. - S3 buckets - There are no special requirements for settingEvaluateTargetHealth
totrue
when the alias target is an S3 bucket. - Other records in the same hosted zone - If the AWS resource that you specify inDNSName
is a record or a group of records (for example, a group of weighted records) but is not another alias record, we recommend that you associate a health check with all of the records in the alias target. For more information, see What Happens When You Omit Health Checks? in the Amazon Route 53 Developer Guide . For more information and examples, see Amazon Route 53 Health Checks and DNS Failover in the Amazon Route 53 Developer Guide .

Amazon API Gateway custom regional APIs and edge-optimized APIs - Specify the applicable domain name for your API. You can get the applicable value using the AWS CLI command get-domain-names :
For regional APIs, specify the value of
regionalDomainName
.For edge-optimized APIs, specify the value of
distributionDomainName
. This is the name of the associated CloudFront distribution, such asda1b2c3d4e5.cloudfront.net
.
The name of the record that you’re creating must match a custom domain name for your API, such as

using the AWS CLI command describe-vpc-endpoints .CloudFront distribution - Specify the domain name that CloudFront assigned when you created your distribution.
Your CloudFront distribution must include an alternate domain name that matches the name of the record. For example, if the name of the record is acme.example.com , your CloudFront distribution must include acme.example.com as one of the alternate domain names. For more information, see Using Alternate Domain Names (CNAMEs) in the Amazon CloudFront Developer Guide .
You can’t create a record in a private hosted zone to route traffic to a CloudFront distribution. .. epigraph:
For failover alias records, you can't specify a CloudFront distribution for both the primary and secondary records. A distribution must include an alternate domain name that matches the name of the record. However, the primary and secondary records have the same name, and you can't include the same alternate domain name in more than one distribution.
Elastic Beanstalk environment - If the domain name for your Elastic Beanstalk environment includes the region that you deployed the environment in, you can create an alias record that routes traffic to the environment. For example, the domain name
my-environment. *us-west-2* .elasticbeanstalk.com
is a regionalized domain name.
For environments that were created before early 2016, the domain name doesn’t include the region. To route traffic to these environments, you must create a CNAME record instead of an alias record. Note that you can’t create a CNAME record for the root domain name. For example, if your domain name is example.com, you can create a record that routes traffic for acme.example.com to your Elastic Beanstalk environment, but you can’t create a record that routes traffic for example.com to your Elastic Beanstalk environment.
For Elastic Beanstalk environments that have regionalized subdomains, specify the

when the alias target is a CloudFront distribution.Elastic Beanstalk environments that have regionalized subdomains - If you specify an Elastic Beanstalk environment in
DNSName
and the environment contains an ELB load balancer, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. (An environment automatically contains an ELB load balancer if it includes more than one Amazon EC2 instance.) If you setEvaluateTargetHealth
totrue
and either no Amazon EC2 instances are healthy or the load balancer itself is unhealthy, Route 53 routes queries to other available resources that are healthy, if any.
If the environment contains a single Amazon EC2 instance, there are no special requirements.
ELB load balancers - Health checking behavior depends on the type of load balancer:
Classic Load Balancers : If you specify an ELB Classic Load Balancer in
DNSName
, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. If you setEvaluateTargetHealth
totrue
and either no EC2 instances are healthy or the load balancer itself is unhealthy, Route 53 routes queries to other resources.Application and Network Load Balancers : If you specify an ELB Application or Network Load Balancer and you set
EvaluateTargetHealth
totrue
, Route 53 routes queries to the load balancer based on the health of the target groups that are associated with the load balancer:For an Application or Network Load Balancer to be considered healthy, every target group that contains targets must contain at least one healthy target. If any target group contains only unhealthy targets, the load balancer is considered unhealthy, and Route 53 routes queries to other resources.
A target group that has no registered targets is considered unhealthy.
When you create a load balancer, you configure settings for Elastic Load Balancing health checks; they’re not Route 53 health checks, but they perform a similar function. Do not create Route 53 health checks for the EC2 instances that you register with an ELB load balancer.
S3 buckets - There are no special requirements for setting
EvaluateTargetHealth
totrue
when the alias target is an S3 bucket.Other records in the same hosted zone - If the AWS resource that you specify in
DNSName
is a record or a group of records (for example, a group of weighted records) but is not another alias record, we recommend that you associate a health check with all of the records in the alias target. For more information, see What Happens When You Omit Health Checks? in the Amazon Route 53 Developer Guide .

) – ForChangeResourceRecordSets
requests, the name of the record that you want to create, update, or delete. ForListResourceRecordSets
responses, the name of a record in the specified hosted zone. ChangeResourceRecordSets Only Enter a fully qualified domain name, for example,www.example.com
. You can optionally include a trailing dot. If you omit the trailing dot, Amazon Route 53 assumes that the domain name that you specify is fully qualified. This means that Route 53 treatswww.example.com
(without a trailing dot) andwww.example.com.
(with a trailing dot) as identical. For information about how to specify characters other thana-z
,0-9
, and-
(hyphen) and how to specify internationalized domain names, see DNS Domain Name Format in the Amazon Route 53 Developer Guide . You can use the asterisk (*) wildcard to replace the leftmost label in a domain name, for example,*.example.com
. Note the following: - The * must replace the entire label. For example, you can’t specify*prod.example.com
orprod*.example.com
. - The * can’t replace any of the middle labels, for example, marketing.*.example.com. - If you include * in any position other than the leftmost label in a domain name, DNS treats it as an * character (ASCII 42), not as a wildcard. .. epigraph:: You can’t use the * wildcard for resource records sets that have a type of NS.type (

.. epigraph:: SPF records were formerly used to verify the identity of the sender of email messages. However, we no longer recommend that you create resource record sets for which the value ofType
isSPF
. RFC 7208, Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1 , has been updated to say, “…[I]ts existence and mechanism defined in [RFC4408] have led to some interoperability issues. Accordingly, its use is no longer appropriate for SPF version 1; implementations are not to use it.” In RFC 7208, see section 14.1, The SPF DNS Record Type . Values for alias resource record sets: - Amazon API Gateway custom regional APIs and edge-optimized APIs:A
- CloudFront distributions:A
If IPv6 is enabled for the distribution, create two resource record sets to route traffic to your distribution, one with a value ofA
and one with a value ofAAAA
. - Amazon API Gateway environment that has a regionalized subdomain :A
- ELB load balancers:A

- Amazon S3 buckets:A
- Amazon Virtual Private Cloud interface VPC endpointsA
- Another resource record set in this hosted zone: Specify the type of the resource record set that you’re creating the alias for. All values are supported exceptNS
andSOA
. .. epigraph:: If you’re creating an alias record that has the same name as the hosted zone (known as the zone apex), you can’t route traffic to a record for which the value ofType
isCNAME
. This is because the alias record must have the same type as the record you’re routing traffic to, and creating a CNAME record for the zone apex isn’t supported even for an alias record.alias_target (

]) –failover (
Optional
[str
]) –Failover resource record sets only: To configure failover, you add the
Failover
element to two resource record sets. For one resource record set, you specifyPRIMARY
as the value forFailover
; for the other resource record set, you specifySECONDARY
. In addition, you include theHealthCheckId
element and specify the health check that you want Amazon Route 53 to perform for each resource record set. Except where noted, the following failover behaviors assume that you have included theHealthCheckId
element in both resource record sets: - When the primary resource record set is healthy, Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the secondary resource record set. - When the primary resource record set is unhealthy and the secondary resource record set is healthy, Route 53 responds to DNS queries with the applicable value from the secondary resource record set. - When the secondary resource record set is unhealthy, Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the primary resource record set. - If you omit theHealthCheckId
element for the secondary resource record set, and if the primary resource record set is unhealthy, Route 53 always responds to DNS queries with the applicable value from the secondary resource record set. This is true regardless of the health of the associated endpoint. You can’t create non-failover resource record sets that have the same values for theName
andType
elements as failover resource record sets. For failover alias resource record sets, you must also include theEvaluateTargetHealth
element and set the value to true. For more information about configuring failover for Route 53, see the following topics in the Amazon Route 53 Developer Guide : - Route 53 Health Checks and DNS Failover - Configuring Failover in a Private Hosted Zonegeo_location (
Union
[IResolvable
,GeoLocationProperty
,Dict
[str
,Any
],None
]) – Geolocation resource record sets only: A complex type that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query. For example, if you want all queries from Africa to be routed to a web server with an IP address of192.0.2.111
, create a resource record set with aType
ofA
and aContinentCode
ofAF
. If you create separate resource record sets for overlapping geographic regions (for example, one resource record set for a continent and one for a country on the same continent), priority goes to the smallest geographic region. This allows you to route most queries for a continent to one resource and to route queries for a country on that continent to a different resource. You can’t create two geolocation resource record sets that specify the same geographic location. The value*
in theCountryCode
element matches all geographic locations that aren’t specified in other geolocation resource record sets that have the same values for theName
andType
elements. .. epigraph:: Geolocation works by mapping IP addresses to locations. However, some IP addresses aren’t mapped to geographic locations, so even if you create geolocation resource record sets that cover all seven continents, Route 53 will receive some DNS queries from locations that it can’t identify. We recommend that you create a resource record set for which the value ofCountryCode
is*
. Two groups of queries are routed to the resource that you specify in this record: queries that come from locations for which you haven’t created geolocation resource record sets and queries from IP addresses that aren’t mapped to a location. If you don’t create a*
resource record set, Route 53 returns a “no answer” response for queries from those locations. You can’t create non-geolocation resource record sets that have the same values for theName
andType
elements as geolocation resource record sets.geo_proximity_location (
Union
[IResolvable
,GeoProximityLocationProperty
,Dict
[str
,Any
],None
]) – A complex type that contains information about a geographic location.health_check_id (
Optional
[str
]) –If you want Amazon Route 53 to return this resource record set in response to a DNS query only when the status of a health check is healthy, include the
HealthCheckId
element and specify the ID of the applicable health check. Route 53 determines whether a resource record set is healthy based on one of the following: - By periodically sending a request to the endpoint that is specified in the health check - By aggregating the status of a specified group of health checks (calculated health checks) - By determining the current state of a CloudWatch alarm (CloudWatch metric health checks) .. epigraph:: Route 53 doesn’t check the health of the endpoint that is specified in the resource record set, for example, the endpoint specified by the IP address in theValue
element. When you add aHealthCheckId
element to a resource record set, Route 53 checks the health of the endpoint that you specified in the health check. For more information, see the following topics in the Amazon Route 53 Developer Guide : - How Amazon Route 53 Determines Whether an Endpoint Is Healthy - Route 53 Health Checks and DNS Failover - Configuring Failover in a Private Hosted Zone When to Specify HealthCheckId Specifying a value forHealthCheckId
is useful only when Route 53 is choosing between two or more resource record sets to respond to a DNS query, and you want Route 53 to base the choice in part on the status of a health check. Configuring health checks makes sense only in the following configurations: - Non-alias resource record sets : You’re checking the health of a group of non-alias resource record sets that have the same routing policy, name, and type (such as multiple weighted records named www.example.com with a type of A) and you specify health check IDs for all the resource record sets. If the health check status for a resource record set is healthy, Route 53 includes the record among the records that it responds to DNS queries with. If the health check status for a resource record set is unhealthy, Route 53 stops responding to DNS queries using the value for that resource record set. If the health check status for all resource record sets in the group is unhealthy, Route 53 considers all resource record sets in the group healthy and responds to DNS queries accordingly. - Alias resource record sets : You specify the following settings: - You setEvaluateTargetHealth
to true for an alias resource record set in a group of resource record sets that have the same routing policy, name, and type (such as multiple weighted records named www.example.com with a type of A). - You configure the alias resource record set to route traffic to a non-alias resource record set in the same hosted zone. - You specify a health check ID for the non-alias resource record set. If the health check status is healthy, Route 53 considers the alias resource record set to be healthy and includes the alias record among the records that it responds to DNS queries with. If the health check status is unhealthy, Route 53 stops responding to DNS queries using the alias resource record set. .. epigraph:: The alias resource record set can also route traffic to a group of non-alias resource record sets that have the same routing policy, name, and type. In that configuration, associate health checks with all of the resource record sets in the group of non-alias resource record sets. Geolocation Routing For geolocation resource record sets, if an endpoint is unhealthy, Route 53 looks for a resource record set for the larger, associated geographic region. For example, suppose you have resource record sets for a state in the United States, for the entire United States, for North America, and a resource record set that has*
forCountryCode
is*
, which applies to all locations. If the endpoint for the state resource record set is unhealthy, Route 53 checks for healthy resource record sets in the following order until it finds a resource record set for which the endpoint is healthy: - The United States - North America - The default resource record set Specifying the Health Check Endpoint by Domain Name If your health checks specify the endpoint only by domain name, we recommend that you create a separate health check for each endpoint. For example, create a health check for eachHTTP
server that is serving content forwww.example.com
. For the value ofFullyQualifiedDomainName
, specify the domain name of the server (such asus-east-2-www.example.com
), not the name of the resource record sets (www.example.com
). .. epigraph:: Health check results will be unpredictable if you do the following: - Create a health check that has the same value forFullyQualifiedDomainName
as the name of a resource record set. - Associate that health check with the resource record set.hosted_zone_id (
Optional
[str
]) – The ID of the hosted zone that you want to create records in. Specify eitherHostedZoneName
orHostedZoneId
, but not both. If you have multiple hosted zones with the same domain name, you must specify the hosted zone usingHostedZoneId
. Do not provide theHostedZoneId
if it is already defined inAWS::Route53::RecordSetGroup
. The creation fails ifHostedZoneId
is defined in both.hosted_zone_name (
Optional
[str
]) – The name of the hosted zone that you want to create records in. You must include a trailing dot (for example,www.example.com.
) as part of theHostedZoneName
. When you create a stack using anAWS::Route53::RecordSet
that specifiesHostedZoneName
, AWS CloudFormation attempts to find a hosted zone whose name matches theHostedZoneName
. If AWS CloudFormation can’t find a hosted zone with a matching domain name, or if there is more than one hosted zone with the specified domain name, AWS CloudFormation will not create the stack. Specify eitherHostedZoneName
orHostedZoneId
, but not both. If you have multiple hosted zones with the same domain name, you must specify the hosted zone usingHostedZoneId
.multi_value_answer (
Union
[bool
,IResolvable
,None
]) – Multivalue answer resource record sets only : To route traffic approximately randomly to multiple resources, such as web servers, create one multivalue answer record for each resource and specifytrue
forMultiValueAnswer
. Note the following: - If you associate a health check with a multivalue answer resource record set, Amazon Route 53 responds to DNS queries with the corresponding IP address only when the health check is healthy. - If you don’t associate a health check with a multivalue answer record, Route 53 always considers the record to be healthy. - Route 53 responds to DNS queries with up to eight healthy records; if you have eight or fewer healthy records, Route 53 responds to all DNS queries with all the healthy records. - If you have more than eight healthy records, Route 53 responds to different DNS resolvers with different combinations of healthy records. - When all records are unhealthy, Route 53 responds to DNS queries with up to eight unhealthy records. - If a resource becomes unavailable after a resolver caches a response, client software typically tries another of the IP addresses in the response. You can’t create multivalue answer alias records.region (
Optional
[str
]) – Latency-based resource record sets only: The Amazon EC2 Region where you created the resource that this resource record set refers to. The resource typically is an AWS resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP address or a DNS domain name, depending on the record type. When Amazon Route 53 receives a DNS query for a domain name and type for which you have created latency resource record sets, Route 53 selects the latency resource record set that has the lowest latency between the end user and the associated Amazon EC2 Region. Route 53 then returns the value that is associated with the selected resource record set. Note the following: - You can only specify oneResourceRecord
per latency resource record set. - You can only create one latency resource record set for each Amazon EC2 Region. - You aren’t required to create latency resource record sets for all Amazon EC2 Regions. Route 53 will choose the region with the best latency from among the regions that you create latency resource record sets for. - You can’t create non-latency resource record sets that have the same values for theName
andType
elements as latency resource record sets.resource_records (
Optional
[Sequence
[str
]]) – Information about the records that you want to create. Each record should be in the format appropriate for the record type specified by theType
property. For information about different record types and their record formats, see Values That You Specify When You Create or Edit Amazon Route 53 Records in the Amazon Route 53 Developer Guide .set_identifier (
Optional
[str
]) – Resource record sets that have a routing policy other than simple: An identifier that differentiates among multiple resource record sets that have the same combination of name and type, such as multiple weighted resource record sets named acme.example.com that have a type of A. In a group of resource record sets that have the same name and type, the value ofSetIdentifier
must be unique for each resource record set. For information about routing policies, see Choosing a Routing Policy in the Amazon Route 53 Developer Guide .ttl (
Optional
[str
]) – The resource record cache time to live (TTL), in seconds. Note the following:. - If you’re creating or updating an alias resource record set, omitTTL
. Amazon Route 53 uses the value ofTTL

]) – Weighted resource record sets only: Among resource record sets that have the same combination of DNS name and type, a value that determines the proportion of DNS queries that Amazon Route 53 responds to using the current resource record set. Route 53 calculates the sum of the weights for the resource record sets that have the same combination of DNS name and type. Route 53 then responds to queries based on the ratio of a resource’s weight to the total. Note the following: - You must specify a value for theWeight
element for every weighted resource record set. - You can only specify oneResourceRecord
per weighted resource record set. - You can’t create latency, failover, or geolocation resource record sets that have the same values for theName

to0
for a resource record set, Route 53 never responds to queries with the applicable value for that resource record set. However, if you setWeight
to0
for all resource record sets that have the same combination of DNS name and type, traffic is routed to all resources with equal probability. The effect of settingWeight
to0
is different when you associate health checks with weighted resource record sets. For more information, see Options for Configuring Route 53 Active-Active and Active-Passive Failover in the Amazon Route 53 Developer Guide .

Attributes
- alias_target
Information about the AWS resource, such as a CloudFront distribution or an Amazon S3 bucket, that you want to route traffic to.
If you’re creating resource records sets for a private hosted zone, note the following:
You can’t create an alias resource record set in a private hosted zone to route traffic to a CloudFront distribution.

- failover
To configure failover, you add the
Failover
element to two resource record sets.
For one resource record set, you specify
PRIMARY
as the value forFailover
; for the other resource record set, you specifySECONDARY
. In addition, you include theHealthCheckId
element and specify the health check that you want Amazon Route 53 to perform for each resource record set.Except where noted, the following failover behaviors assume that you have included the
HealthCheckId
element in both resource record sets:When the primary resource record set is healthy, Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the secondary resource record set.
When the primary resource record set is unhealthy and the secondary resource record set is healthy, Route 53 responds to DNS queries with the applicable value from the secondary resource record set.
When the secondary resource record set is unhealthy, Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the primary resource record set.
If you omit the
HealthCheckId
element for the secondary resource record set, and if the primary resource record set is unhealthy, Route 53 always responds to DNS queries with the applicable value from the secondary resource record set. This is true regardless of the health of the associated endpoint.
You can’t create non-failover resource record sets that have the same values for the
Name
andType
elements as failover resource record sets.For failover alias resource record sets, you must also include the
EvaluateTargetHealth
element and set the value to true.For more information about configuring failover for Route 53, see the following topics in the Amazon Route 53 Developer Guide :
- See:
- Type:
*Failover resource record sets only
- geo_location
A complex type that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query.
For example, if you want all queries from Africa to be routed to a web server with an IP address of
192.0.2.111
, create a resource record set with aType
ofA
and aContinentCode
ofAF
.If you create separate resource record sets for overlapping geographic regions (for example, one resource record set for a continent and one for a country on the same continent), priority goes to the smallest geographic region. This allows you to route most queries for a continent to one resource and to route queries for a country on that continent to a different resource.
You can’t create two geolocation resource record sets that specify the same geographic location.
The value
*
in theCountryCode
element matches all geographic locations that aren’t specified in other geolocation resource record sets that have the same values for theName
andType
elements. .. epigraph:Geolocation works by mapping IP addresses to locations. However, some IP addresses aren't mapped to geographic locations, so even if you create geolocation resource record sets that cover all seven continents, Route 53 will receive some DNS queries from locations that it can't identify. We recommend that you create a resource record set for which the value of ``CountryCode`` is ``*`` . Two groups of queries are routed to the resource that you specify in this record: queries that come from locations for which you haven't created geolocation resource record sets and queries from IP addresses that aren't mapped to a location. If you don't create a ``*`` resource record set, Route 53 returns a "no answer" response for queries from those locations.
You can’t create non-geolocation resource record sets that have the same values for the
Name
andType
elements as geolocation resource record sets.- See:
- Type:
*Geolocation resource record sets only
- geo_proximity_location
A complex type that contains information about a geographic location.
- health_check_id
If you want Amazon Route 53 to return this resource record set in response to a DNS query only when the status of a health check is healthy, include the
HealthCheckId
element and specify the ID of the applicable health check.Route 53 determines whether a resource record set is healthy based on one of the following:
By periodically sending a request to the endpoint that is specified in the health check
By aggregating the status of a specified group of health checks (calculated health checks)
By determining the current state of a CloudWatch alarm (CloudWatch metric health checks)
Route 53 doesn’t check the health of the endpoint that is specified in the resource record set, for example, the endpoint specified by the IP address in the
Value
element. When you add aHealthCheckId
element to a resource record set, Route 53 checks the health of the endpoint that you specified in the health check.For more information, see the following topics in the Amazon Route 53 Developer Guide :
When to Specify HealthCheckId
Specifying a value for
HealthCheckId
is useful only when Route 53 is choosing between two or more resource record sets to respond to a DNS query, and you want Route 53 to base the choice in part on the status of a health check. Configuring health checks makes sense only in the following configurations:Non-alias resource record sets : You’re checking the health of a group of non-alias resource record sets that have the same routing policy, name, and type (such as multiple weighted records named www.example.com with a type of A) and you specify health check IDs for all the resource record sets.
If the health check status for a resource record set is healthy, Route 53 includes the record among the records that it responds to DNS queries with.
If the health check status for a resource record set is unhealthy, Route 53 stops responding to DNS queries using the value for that resource record set.
If the health check status for all resource record sets in the group is unhealthy, Route 53 considers all resource record sets in the group healthy and responds to DNS queries accordingly.
Alias resource record sets : You specify the following settings:
You set
EvaluateTargetHealth
to true for an alias resource record set in a group of resource record sets that have the same routing policy, name, and type (such as multiple weighted records named www.example.com with a type of A).You configure the alias resource record set to route traffic to a non-alias resource record set in the same hosted zone.
You specify a health check ID for the non-alias resource record set.
If the health check status is healthy, Route 53 considers the alias resource record set to be healthy and includes the alias record among the records that it responds to DNS queries with.
If the health check status is unhealthy, Route 53 stops responding to DNS queries using the alias resource record set. .. epigraph:
The alias resource record set can also route traffic to a *group* of non-alias resource record sets that have the same routing policy, name, and type. In that configuration, associate health checks with all of the resource record sets in the group of non-alias resource record sets.
Geolocation Routing
For geolocation resource record sets, if an endpoint is unhealthy, Route 53 looks for a resource record set for the larger, associated geographic region. For example, suppose you have resource record sets for a state in the United States, for the entire United States, for North America, and a resource record set that has
*
forCountryCode
is*
, which applies to all locations. If the endpoint for the state resource record set is unhealthy, Route 53 checks for healthy resource record sets in the following order until it finds a resource record set for which the endpoint is healthy:The United States
North America
The default resource record set
Specifying the Health Check Endpoint by Domain Name
If your health checks specify the endpoint only by domain name, we recommend that you create a separate health check for each endpoint. For example, create a health check for each
HTTP
server that is serving content forwww.example.com
. For the value ofFullyQualifiedDomainName
, specify the domain name of the server (such asus-east-2-www.example.com
), not the name of the resource record sets (www.example.com
). .. epigraph:Health check results will be unpredictable if you do the following: - Create a health check that has the same value for ``FullyQualifiedDomainName`` as the name of a resource record set. - Associate that health check with the resource record set.
- hosted_zone_id
The ID of the hosted zone that you want to create records in.
Specify either
HostedZoneName
orHostedZoneId
, but not both. If you have multiple hosted zones with the same domain name, you must specify the hosted zone usingHostedZoneId
.Do not provide the
HostedZoneId
if it is already defined inAWS::Route53::RecordSetGroup
. The creation fails ifHostedZoneId
is defined in both.
- hosted_zone_name
The name of the hosted zone that you want to create records in.
You must include a trailing dot (for example,
www.example.com.
) as part of theHostedZoneName
.When you create a stack using an
AWS::Route53::RecordSet
that specifiesHostedZoneName
, AWS CloudFormation attempts to find a hosted zone whose name matches theHostedZoneName
. If AWS CloudFormation can’t find a hosted zone with a matching domain name, or if there is more than one hosted zone with the specified domain name, AWS CloudFormation will not create the stack.Specify either
HostedZoneName
orHostedZoneId
, but not both. If you have multiple hosted zones with the same domain name, you must specify the hosted zone usingHostedZoneId
.
- multi_value_answer
To route traffic approximately randomly to multiple resources, such as web servers, create one multivalue answer record for each resource and specify
true
forMultiValueAnswer
.Note the following:
If you associate a health check with a multivalue answer resource record set, Amazon Route 53 responds to DNS queries with the corresponding IP address only when the health check is healthy.
If you don’t associate a health check with a multivalue answer record, Route 53 always considers the record to be healthy.
Route 53 responds to DNS queries with up to eight healthy records; if you have eight or fewer healthy records, Route 53 responds to all DNS queries with all the healthy records.
If you have more than eight healthy records, Route 53 responds to different DNS resolvers with different combinations of healthy records.
When all records are unhealthy, Route 53 responds to DNS queries with up to eight unhealthy records.
If a resource becomes unavailable after a resolver caches a response, client software typically tries another of the IP addresses in the response.
You can’t create multivalue answer alias records.
- See:
- Type:
Multivalue answer resource record sets only
- name
For
ChangeResourceRecordSets
requests, the name of the record that you want to create, update, or delete.For
ListResourceRecordSets
responses, the name of a record in the specified hosted zone.ChangeResourceRecordSets Only
Enter a fully qualified domain name, for example,
www.example.com
. You can optionally include a trailing dot. If you omit the trailing dot, Amazon Route 53 assumes that the domain name that you specify is fully qualified. This means that Route 53 treatswww.example.com
(without a trailing dot) andwww.example.com.
(with a trailing dot) as identical.For information about how to specify characters other than
a-z
,0-9
, and-
(hyphen) and how to specify internationalized domain names, see DNS Domain Name Format in the Amazon Route 53 Developer Guide .You can use the asterisk (*) wildcard to replace the leftmost label in a domain name, for example,
*.example.com
. Note the following:The * must replace the entire label. For example, you can’t specify
*prod.example.com
orprod*.example.com
.The * can’t replace any of the middle labels, for example, marketing.*.example.com.
If you include * in any position other than the leftmost label in a domain name, DNS treats it as an * character (ASCII 42), not as a wildcard.
You can’t use the * wildcard for resource records sets that have a type of NS.
- region
The Amazon EC2 Region where you created the resource that this resource record set refers to.
The resource typically is an AWS resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP address or a DNS domain name, depending on the record type.
When Amazon Route 53 receives a DNS query for a domain name and type for which you have created latency resource record sets, Route 53 selects the latency resource record set that has the lowest latency between the end user and the associated Amazon EC2 Region. Route 53 then returns the value that is associated with the selected resource record set.
Note the following:
You can only specify one
ResourceRecord
per latency resource record set.You can only create one latency resource record set for each Amazon EC2 Region.
You aren’t required to create latency resource record sets for all Amazon EC2 Regions. Route 53 will choose the region with the best latency from among the regions that you create latency resource record sets for.
You can’t create non-latency resource record sets that have the same values for the
Name
andType
elements as latency resource record sets.
- See:
- Type:
*Latency-based resource record sets only
- resource_records
Information about the records that you want to create.
Each record should be in the format appropriate for the record type specified by the
Type

- set_identifier
An identifier that differentiates among multiple resource record sets that have the same combination of name and type, such as multiple weighted resource record sets named acme.example.com that have a type of A. In a group of resource record sets that have the same name and type, the value of
SetIdentifier
must be unique for each resource record set.

- ttl
.
If you’re creating or updating an alias resource record set, omit
TTL
. Amazon Route 53 uses the value ofTTL
for the alias target.If you’re associating this resource record set with a health check (if you’re adding a
HealthCheckId
element), we recommend that you specify aTTL
of 60 seconds or less so clients respond quickly to changes in health status.All of the resource record sets in a group of weighted resource record sets must have the same value for
TTL
.If a group of weighted resource record sets includes one or more weighted alias resource record sets for which the alias target is an ELB load balancer, we recommend that you specify a
TTL
of 60 seconds for all of the non-alias weighted resource record sets that have the same name and type. Values other than 60 seconds (the TTL for load balancers) will change the effect of the values that you specify forWeight
.

.. epigraph:SPF records were formerly used to verify the identity of the sender of email messages. However, we no longer recommend that you create resource record sets for which the value of ``Type`` is ``SPF`` . RFC 7208, *Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1* , has been updated to say, "...[I]ts existence and mechanism defined in [RFC4408] have led to some interoperability issues. Accordingly, its use is no longer appropriate for SPF version 1; implementations are not to use it." In RFC 7208, see section 14.1, `The SPF DNS Record Type <https://docs.aws.amazon.com/http://tools.ietf.org/html/rfc7208#section-14.1>`_ .

Another resource record set in this hosted zone: Specify the type of the resource record set that you’re creating the alias for. All values are supported except
NS
andSOA
.
If you’re creating an alias record that has the same name as the hosted zone (known as the zone apex), you can’t route traffic to a record for which the value of
Type
isCNAME
. This is because the alias record must have the same type as the record you’re routing traffic to, and creating a CNAME record for the zone apex isn’t supported even for an alias record.
- weight
Among resource record sets that have the same combination of DNS name and type, a value that determines the proportion of DNS queries that Amazon Route 53 responds to using the current resource record set.
Route 53 calculates the sum of the weights for the resource record sets that have the same combination of DNS name and type. Route 53 then responds to queries based on the ratio of a resource’s weight to the total. Note the following:
You must specify a value for the
Weight
element for every weighted resource record set.You can only specify one
ResourceRecord
per weighted resource record set.You can’t create latency, failover, or geolocation resource record sets that have the same values for the
Name
andType
elements as weighted resource record sets.You can create a maximum of 100 weighted resource record sets that have the same values for the
Name
andType
elements.For weighted (but not weighted alias) resource record sets, if you set
Weight
to0
for a resource record set, Route 53 never responds to queries with the applicable value for that resource record set. However, if you setWeight
to0
for all resource record sets that have the same combination of DNS name and type, traffic is routed to all resources with equal probability.
The effect of setting
Weight
to0
is different when you associate health checks with weighted resource record sets. For more information, see Options for Configuring Route 53 Active-Active and Active-Passive Failover in the Amazon Route 53 Developer Guide .- See:
