This update allows customers using AWS GovCloud (US-East and US-West) to delegate subdomains between on-premises DNS infrastructure and Route 53 Resolver endpoints, facilitating flexible namespace management while maintaining centralized apex domain control. Previously available only in commercial regions, this feature streamlines DNS management without the need for conditional forwarding rules.
The inbound and outbound delegation enables operational simplicity and consistency for organizations with hybrid environments, and is provided at no extra cost atop standard Resolver endpoint usage. This supports complex organizational needs regarding domain delegation in restricted AWS regions.
