Values specific for simple alias records - Amazon Route 53

Values specific for simple alias records

When you create alias records, you specify the following values. For more information, see Choosing between alias and non-alias records.

Note

If you are using Route 53 in the AWS GovCloud (US) Region, this feature has some restrictions. For more information, see the Amazon Route 53 page in the AWS GovCloud (US) User Guide.

Routing policy

Choose Simple routing.

Record name

Enter the name of the domain or subdomain that you want to route traffic for. The default value is the name of the hosted zone.

Note

If you're creating a record that has the same name as the hosted zone, don't enter a value (for example, an @ symbol) in the Name field.

For more information about record names, see Record name.

Value/route traffic to

The value that you choose from the list or that you type in the field depends on the AWS resource that you're routing traffic to.

For information about what AWS resources you can target, see Value/route traffic to.

For more information about how to configure Route 53 to route traffic to specific AWS resources, see Routing internet traffic to your AWS resources.

Record type

The DNS record type. For more information, see Supported DNS record types.

Select the applicable value based on the AWS resource that you're routing traffic to:

API Gateway custom regional API or edge-optimized API

Select A — IPv4 address.

Amazon VPC interface endpoints

Select A — IPv4 address.

CloudFront distribution

Select A — IPv4 address.

If IPv6 is enabled for the distribution, create two records, one with a value of A — IPv4 address for Type, and one with a value of AAAA — IPv6 address.

Elastic Beanstalk environment that has regionalized subdomains

Select A — IPv4 address

ELB load balancer

Select A — IPv4 address or AAAA — IPv6 address

Amazon S3 bucket

Select A — IPv4 address

Another record in this hosted zone

Select the type of the record that you're creating the alias for. All types are supported except NS and SOA.

Note

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 is CNAME. 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.

Evaluate target health

When the value of Routing policy is Simple, you can choose either No or the default Yes because Evaluate target health has no effect for Simple routing. If you have only one record that has a given name and type, Route 53 responds to DNS queries by using the values in that record regardless of whether the resource is healthy.
