Amazon Route 53

Route 53 is a highly available and scalable Domain Name System (DNS) web service. In the AWS GovCloud (US), you can use Route 53 private DNS and health checking.

How Amazon Route 53 Differs for AWS GovCloud (US-West) Region

  • Route 53 public hosted zones are not available.

  • Geolocation and latency based routing are not available.

Private Hosted Zones

  • You can create private hosted zones in the AWS GovCloud (US). In general, the functionality is the same as for private hosted zones in the global version of Route 53. However, you can create alias records only when the alias target is another record in the same hosted zone. To route traffic to another AWS resource, such as an ELB load balancer or an S3 bucket, you can use a CNAME record instead of an alias record unless you're creating a record at the zone apex.

Health Checking

  • You can create health checks that monitor endpoints in the AWS GovCloud, and you can create health checks that monitor the status of other health checks.

  • As in other AWS Regions, if you create a health check that monitors an endpoint in the AWS GovCloud, you must make the endpoint available on the public internet. Route 53 health checkers send health checking requests over the public internet.

  • You can restrict access to your endpoints by allowlisting the IP addresses of Route 53 health checkers in the AWS GovCloud:

    • 160.1.56.0/25

    • 160.1.55.0/25

    • 160.1.55.128/25

    • 18.253.167.128/25

    • 18.253.168.0/25

    • 18.253.167.0/25

The control plane for Route 53 in the AWS GovCloud (US) is in the AWS GovCloud (US-West).
