Amazon RDS extends IPv6 support for publicly accessible databases
Amazon Relational Database Service (RDS) now extends the Internet Protocol Version 6 (IPv6) support to publicly accessible databases, in addition to the existing support for privately accessible databases within a VPC. This allows you to configure dual-stack (IPv4 and IPv6) connectivity for your publicly accessible RDS and Aurora databases.
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 AWS regions where IPv6 support for privately accessible RDS databases within a VPC is already available. Get started with the AWS CLI or AWS Management Console.
To learn more about configuring your environment for IPv6, please refer to the IPv6 User Guide.
