AWS IAM Identity Center now supports IPv6

Posted on: Jan 26, 2026

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

IAM Identity Center allows customers to enable workforce access to AWS managed applications and AWS accounts. When your client, such as a browsers 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 AWS Regions where IAM Identity Center is available, except the AWS GovCloud (US) Regions and the Taipei Region. To learn more, visit the IAM Identity Center User Guide.
