Amazon SNS now supports Internet Protocol Version 6 (IPv6)

Amazon SNS now supports Internet Protocol version 6 (IPv6) for API requests enabling you to communicate with Amazon SNS using Internet Protocol Version 6 (IPv6), Internet Protocol Version 4 (IPv4), or dual stack clients using public endpoints.

Amazon SNS is a fully managed messaging service that enables publish/subscribe messaging between distributed systems, microservices, and event-driven serverless applications. The addition of IPv6 support provides customers with a vastly expanded address space, eliminating concerns about address exhaustion and simplifying network architecture for IPv6-native applications. With simultaneous support for both IPv4 and IPv6 clients on SNS public endpoints, customers can gradually transition from IPv4 to IPv6-based systems and applications without needing to switch all systems at once. This enhancement is particularly valuable for modern cloud-native applications and organizations transitioning to IPv6 as part of their modernization efforts.

To learn more on best practices for configuring IPv6 in your environment, visit the whitepaper on IPv6 in AWS. This feature is now available in all AWS commercial Regions, including AWS China Regions, and can be used at no additional cost.
