Amazon IAM Identity Center now supports IPv6

Posted on: Jan 27, 2026

Amazon IAM Identity Center now supports Internet Protocol version 6 (IPv6) through new dual-stack endpoints. Customers can now connect to Amazon IAM Identity Center using IPv6, IPv4, or dual-stack clients. The existing Amazon IAM Identity Center endpoints supporting IPv4 remain available for backward compatibility.

IAM Identity Center allows customers to enable workforce access to Amazon managed applications and accounts. When your client, such as a browser or an application, makes a request to a dual-stack endpoint, the endpoint resolves to an IPv4 or IPv6 address, depending on the protocol used by your network and client. This launch helps you meet IPv6 compliance requirements and minimize the need for complex NAT infrastructure. 

IPv6 support is available in all Regions where IAM Identity Center is available, including Amazon Web Services China (Beijing) region, operated by Sinnet, and Amazon Web Services China (Ningxia) region, operated by NWCD. To learn more, visit the IAM Identity Center User Guide.
