Amazon Route 53 Resolver now allows private access through AWS PrivateLink, enabling users to manage its features without using the public internet. This includes operations like creating and managing DNS records securely over the Amazon network. It is available in all VPCs and supports various AWS regions, including GovCloud.

Amazon Route 53 Resolver endpoints now support DNS delegation for private hosted zones, allowing users to delegate authority for subdomains between on-premises infrastructure and the cloud. This simplifies DNS management for organizations by removing the need for complex conditional forwarding rules. The feature is globally available at no additional cost in supported AWS regions.
