Thank you everyone who responded to our recent IPv6 migration survey! We want you to know that we are committed to improving your IPv6 journey and these data are helpful in shaping our future plans.

To that end, just a quick update: we are committing to expanding our CLAT support to include non-cellular network interfaces in a future version of Windows 11. This will include discovery using the relevant parts of RFC 7050 (ipv4only.arpa DNS query), RFC 8781 (PREF64 option in RAs), and RFC 8925 (DHCP Option 108) standards. Once we do have functionality available for you to test in Windows Insiders builds, we will let you know.

We are looking forward to continuing to provide support for your platform networking needs!

    While I'll readily admit to being a critic of Microsoft's missteps (particularly regarding IPv6 support), that means I also have to acknowledge the wins, too. :lol:

    Thank you for listening to the community on this! This will make IPv6-only networks a lot more viable.

    Bad news, that "future version of Windows 11" isn't 24H2.  I connected my new Wi-Fi 7 computer to my IPv6-mostly network, and I'm still forced to use IPv4.  Somewhere else on the Internet, I was told to use `netsh interface ipv6 show prefixpolicies` to see and re-rank prefix policies, but "464XLAT" is nowhere to be found, not even for early adopters who know how to file bug reports.

    I believe such important feature to users is simply not in Microsoft's playbook. The engineer who dared to give this feature would be kicked out of the job or made to sit in a dark room till he/she comes up with 10 ways to display more ads or monetize this feature before being let free. So I don't believe such feature could ever come to Windows.
