AWS extended support for IPv6 to Virtual Private Cloud endpoints of its RDS Service APIs, complementing existing IPv6 support for public endpoints. This enhancement allows customers to access RDS APIs within their private networks without internet traversal, supporting greater address space and scalability.
The dual-stack capability facilitates progressive transition from IPv4 to IPv6 addressing, enabling easier management of contiguous IP ranges for microservices and large-scale applications. The feature is available across all commercial AWS regions, including GovCloud.
