Amazon Route 53

Amazon 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.

The following list details the differences for using this service in the AWS GovCloud (US-West) Region compared to other AWS Regions:

Private Hosted Zones

  • You can create private hosted zones in the AWS GovCloud (US) with the same functionality as private hosted zones in the global version of Route 53.

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.

  • Route 53 doesn't support creating health checks that monitor the status of CloudWatch alarms in the AWS GovCloud.

  • 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 whitelisting 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

For more information about Amazon Route 53, see the Amazon Route 53 documentation.
