IPv6 is cool in theory and the idea of literally everything having its own directly-reachable IP address is extremely compelling, but I never use it because so many services STILL don't support it or don't support it correctly. (As Julia pointed out, some HUGE websites don't have quad-A records, so good luck dealing with NXDOMAIN for like everything.) Shoot, Kubernetes _just_ got support for IPv6 in 1.23 (it was in beta since 1.20). I know that 6to4 exists and many kernels can do it out of the box, but that comes with problems, as Julia rightfully pointed out here, and at that point, you might as well just NAT over IPv4.
