Amazon SNS expands IPv6 support to the AWS GovCloud (US) Regions

Amazon Simple Notification Service (Amazon SNS) now allows customers to make API requests over Internet Protocol version 6 (IPv6) in the AWS GovCloud (US) Regions. The new endpoints have also been validated under the Federal Information Processing Standard (FIPS) 140-3 program.

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 have the option of using either IPv6 or IPv4 when sending requests over dual-stack public or VPC endpoints.

SNS now supports IPv6 in all Regions where the service is available, including AWS Commercial, AWS GovCloud (US), and China Regions. For more information on using IPv6 with Amazon SNS, please refer to our developer guide.
