Amazon Route 53 endpoints and quotas - AWS General Reference

Amazon Route 53 endpoints and quotas

The following are the service endpoints and service quotas for this service. To connect programmatically to an AWS service, you use an endpoint. In addition to the standard AWS endpoints, some AWS services offer FIPS endpoints in selected Regions. For more information, see AWS service endpoints. Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. For more information, see AWS service quotas.

Service endpoints

Hosted zones, records, health checks, DNS query logs, reusable delegation sets, traffic policies, and cost allocation tags

When you use the AWS CLI or SDKs to submit requests, you can either leave the Region and endpoint unspecified, or specify the applicable Region:

  • Route 53 in AWS Regions other than the Beijing and Ningxia Regions: specify us-east-1 as the Region.

  • Route 53 in the Beijing and Ningxia Regions: specify cn-northwest-1.

When you use the Route 53 API to submit requests, use the same Regions as above to sign requests. For more information about signing Route 53 API requests, see Signature Version 4 signing process.
