Windows CLAT is now generally available

Windows 11 25H2, starting with build 26200.9550, now comes with something called CLAT.

As organizations move toward IPv6-only and IPv6-mostly networks, some applications still depend on IPv4-only applications or services. Windows CLAT helps those applications continue to work when a network does not provide native IPv4 connectivity.

CLAT is the client-side component of464XLAT. It statelessly translates IPv4 traffic from the Windows client into IPv6 for transport across the network to a provider-side translator (PLAT), which provides stateful NAT64 translation to IPv4.

Yet another important component of the long, neverending transition to IPv6. Like endlessly cutting a cucumber in half, you'll never quite run out of cucumber to cut.
