Amazon Route 53 Resolver endpoints now support DNS delegation for private hosted zones in AWS GovCloud (US) Regions

Starting today, domain name system (DNS) delegation for private hosted zone subdomains can be used with Route 53 inbound and outbound Resolver endpoints in AWS GovCloud (US) Regions. This allows you to delegate the authority for a subdomain from your on-premises infrastructure to the Route 53 Resolver cloud service and vice versa, enabling a simplified cloud experience across namespaces in AWS and on your own local infrastructure.

Many AWS customers delegate subdomain management to individual teams while maintaining central control of apex domains. Previously, we launched Route 53 Resolver delegation support for private hosted zones in commercial AWS Regions, enabling customers to use standard name server records to delegate subdomain authority between Route 53 and on-premises DNS — eliminating the need for conditional forwarding rules across their organization. With today's release, this delegation capability is now available for Route 53 Resolver endpoints in AWS GovCloud (US-East) and AWS GovCloud (US-West) Regions as well.

Inbound and outbound delegation is provided at no additional cost to Resolver endpoints usage. For more details on pricing, visit the Route 53 pricing page, and to learn more about this feature, visit the developer guide.
