Amazon RDS now supports IPv6 for VPC endpoints of RDS Service APIs
Amazon RDS now supports Internet Protocol version 6 (IPv6) for VPC endpoints of RDS Service APIs, in addition to the existing IPv6 support for public endpoints. This allows you to configure dual-stack (IPv4 and IPv6) connectivity to access RDS Service APIs directly from within your VPC without internet traversal.
IPv6 provides an expanded address space, enabling you to scale your application on AWS beyond the limitations of IPv4 addresses. With IPv6, you can assign easy to manage contiguous IP ranges to micro-services and can get virtually unlimited scale for your applications. Moreover, with support for both IPv4 and IPv6, you can gradually transition applications from IPv4 to IPv6, enabling safer migration.
This feature is available in all commercial AWS regions and AWS GovCloud (US) regions. Get started with the RDS Service APIs here.
