AWS adds IPv6 Support To IAM Identity Center Through Dual-Stack Endpoints
AWS, Tuesday, January 27th, 2026
Amazon Web Services has added IPv6 support to IAM Identity Center through new dual-stack endpoints. The update allows identity services to operate over IPv6 networks while continuing to support IPv4.
The change applies to access portals, managed applications, and service APIs that use dual-stack domain names capable of accepting both IPv4 and IPv6 connections.
Dual-stack endpoints for workforce access
Existing IPv4 endpoints remain available. Clients connect using IPv4, IPv6, or both, depending on operating system and network configuration. Workforce users who need IPv6 access must use the new dual-stack endpoints. Organizations that rely on an external identity provider must also update IdP settings so authentication traffic reaches the dual-stack endpoints.
