When will CloudFront allow IPv6 origins? If it already supports them, can you tell me how?

Amazon CloudFront now supports IPv6 origins for end-to-end IPv6 delivery

IPv6 adoption continues to accelerate worldwide as organizations move beyond the limitations of IPv4 address space. At Amazon Web Services (AWS), we’ve long supported IPv6 from end users to our Amazon CloudFront network, helping end users reduce latency, improve performance, and reach on modern mobile networks. Now, we are excited to take it a step further. Starting today, CloudFront now supports IPv6 connectivity from edge to origin – enabling a truly end-to-end IPv6 delivery path. This enables end users to use CloudFront as an IPv6 and IPv4 dual-stack internet gateway for their web applications to provide content acceleration.

Why this matters?
**IPv6 is the underlying transport protocol for most modern mobile networks and an increasing share of broadband traffic. Enabling IPv6 all the way to the origin allows you to maintain protocol consistency across the delivery chain, reduce operational overhead from dual-stack complexities, and gain more deterministic, observable, and performant traffic flows. For CloudFront end users, these advantages translate directly into faster page loads, more stable streaming, and a delivery architecture that continues to perform as IPv4 resources diminish.
