AWS Identity and Access Management now supports dual-stack (IPv4 and IPv6) environments

[AWS Identity and Access Management (IAM)](https://aws.amazon.com/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 [AWS PrivateLink](https://docs.aws.amazon.com/vpc/latest/privatelink/what-is-privatelink.html). 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 all commercial AWS Regions, the AWS GovCloud (US) Regions, and the China Regions. For more information about IAM dual-stack public endpoint, please see the [IAM User Guide](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference%5Fdual-stack%5Fendpoint%5Fsupport.html).
