The update enables AWS IAM Identity Center to be accessed via IPv6-capable dual-stack endpoints that resolve to IPv4 or IPv6 addresses depending on client and network capabilities. This enhancement allows customers to meet IPv6 compliance needs and reduce reliance on Network Address Translation infrastructure.

Standard IPv4 endpoints remain operational for backward compatibility, but the new dual-stack offering is available in nearly all AWS regions except AWS GovCloud (US) and Taipei. This addition facilitates more streamlined and modern secure identity management connection options within the AWS ecosystem.
