Amazon Identity and Access Management (IAM) announces a new dual-stack public endpoint, enabling customers to connect to IAM over the public internet using IPv6, IPv4, or dual-stack clients. Dual-stack support is also available when customers access the new IAM endpoint privately from their Amazon Virtual Private Cloud (VPC) using Amazon PrivateLink. With simultaneous support for both IPv4 and IPv6 clients on IAM endpoint, customers can gradually transition from IPv4 to IPv6-based systems and applications.

Support for dual-stack IAM endpoint is available in the Amazon Web Services China (Beijing) Region, operated by Sinnet and the Amazon Web Services China (Ningxia) Region, operated by NWCD. For more information about IAM dual-stack public endpoints, please see the IAM User Guide.
