What's New at AWS - Cloud Innovation & News Amazon Relational Database Service (RDS) Proxy now offers customers the option to use Internet Protocol version 6 (IPv6) addresses to pool and share database connections coming from an application. The existing endpoints supporting Internet Protocol version 4 (IPv4) will remain available for backwards compatibility. Additionally, customers now have the option to specify RDS Proxy target connections using either IPv4 or IPv6. The continued growth of the Internet, particularly in the areas of mobile applications, connected devices, and IoT, has spurred an industry-wide move to IPv6. IPv6 increases the number of available addresses by several orders of magnitude so customers no longer need to manage overlapping address spaces in their VPCs. Many applications, including those built on modern serverless architectures, may need to have a high number of open connections to the database or may frequently open and close database connections, exhausting the database memory and compute resources. Amazon RDS Proxy allows applications to pool and share database connections, improving your database efficiency and application scalability. For information on supported database engine versions and regional availability of RDS Proxy, refer to our RDS and Aurora documentations. https://aws.amazon.com/about-aws/whats-new/2025/09/amazon-rds-proxy-supports-ipv6/
