Amazon Simple Notification Service (Amazon SNS) now allows customers to make API requests over Internet Protocol version 6 (IPv6) through AWS PrivateLink with Virtual Private Cloud (VPC) endpoints. This launch extends IPv6 compatibility, previously available only for public endpoints, to VPC endpoints across all AWS commercial Regions.
Amazon SNS is a fully managed messaging service that enables publish/subscribe messaging between distributed systems, microservices, and event-driven serverless applications. With this update, customers can now use VPC Endpoints to privately connect their VPCs to Amazon SNS using IPv6. With simultaneous support for both IPv4 and IPv6 clients on SNS VPC endpoints, customers can gradually transition from IPv4 to IPv6-based systems and applications without needing to switch all systems at once.
IPv6 support for VPC endpoints is now available in all AWS commercial Regions, including AWS China Regions operated by Sinnet and NWCD. For more information on using Amazon SNS with interface VPC endpoints, please refer to our Developer Guide. To learn more about AWS PrivateLink, see accessing AWS services through AWS PrivateLink.
