AWS extended IPv6 support to SFTP and AS2 connectors as well as Transfer Family web applications, enabling connections to remote servers, trading partners, and end-user devices that utilize IPv6. This adaptation addresses partners transitioning away from IPv4 and expands network compatibility.
By offering dual-stack IPv4 and IPv6 support, customers can smoothly migrate their file transfer workflows without service interruption. The enhancement is available across most AWS regions where Transfer Family operates, removing connectivity limitations imposed by legacy internet protocols.
