Information about the record that you want to create.
The AWS::Route53::RecordSet
type can be used as a standalone resource or as an embedded property in the AWS::Route53::RecordSetGroup
type. Note that some AWS::Route53::RecordSet
properties are valid only when used within AWS::Route53::RecordSetGroup
.
For more information, see ChangeResourceRecordSets in the Amazon Route 53 API Reference .

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

public java.lang.Object getGeoLocation()
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 a Type
of A
and a ContinentCode
of AF
.
Although creating geolocation and geolocation alias resource record sets in a private hosted zone is allowed, it's not supported.
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 the CountryCode
element matches all geographic locations that aren't specified in other geolocation resource record sets that have the same values for the Name
and Type
elements.
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

public java.lang.String getHealthCheckId()
Route 53 determines whether a resource record set is healthy based on one of the following:
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:
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.
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).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.
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 *
for CountryCode
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:
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 for www.example.com
. For the value of FullyQualifiedDomainName
, specify the domain name of the server (such as us-east-2-www.example.com
), not the name of the resource record sets ( www.example.com
).
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.
public void setHealthCheckId(java.lang.String value)
Route 53 determines whether a resource record set is healthy based on one of the following:
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.

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).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.
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 *
for CountryCode
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:
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 for www.example.com
. For the value of FullyQualifiedDomainName
, specify the domain name of the server (such as us-east-2-www.example.com
), not the name of the resource record sets ( www.example.com
).
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.
public java.lang.String getHostedZoneId()
Specify either HostedZoneName
or HostedZoneId
, but not both. If you have multiple hosted zones with the same domain name, you must specify the hosted zone using HostedZoneId
.
public void setHostedZoneId(java.lang.String value)
Specify either HostedZoneName
or HostedZoneId
, but not both. If you have multiple hosted zones with the same domain name, you must specify the hosted zone using HostedZoneId
.
public java.lang.String getHostedZoneName()
You must include a trailing dot (for example, www.example.com.
) as part of the HostedZoneName
.
When you create a stack using an AWS::Route53::RecordSet that specifies HostedZoneName
, AWS CloudFormation attempts to find a hosted zone whose name matches the HostedZoneName. If AWS CloudFormation cannot 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.

public java.lang.String getRegion()
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.
