Hello tojens 

Thanks for putting this Technology Survey forward.

 

Some important points to mention about this topic for Windows to improve are the following:

- CLAT support to any Network Interface and not only for WWAN

- Support for RFC8781 (Discovering PREF64 in Router Advertisements)

- Support for RFC8925 (IPv6-Only Preferred Option for DHCPv4)

- Complete support for PCP (Port Control Protocol) to automate the creation of IPv6 Pinholes for applications that require incoming connections (similar to what was previously done by UPnP for IPv4)

 

As an extra thing that is not necessarily related to IPv6 Transition but it is certainly a core network thing to fix is support for /31 prefixes (RFC3021), not only on Windows 11 but on the previous still supported versions.

 

Regards
