IPv6 isn't going to happen. Most people's needs are met by NAT for clients and SNI routing for servers. We ran out of IPv4 addresses years ago. If it was actually a problem it would have happened then. It makes me said for the p2p internet but it's true.

> If it was actually a problem It became a problem precisely the moment AWS starting charging for ipv4 addresses. "IPv4 will cost our company X dollars in 2026, supporting IPv6 by 2026 will cost Y dollars, a Z% saving" There's now a tangible motivator for various corporate systems to at least support ipv6 everywhere - which was the real ipv6 impediment. Residential ISP appear to be very capable of moving to v6, there are lots of examples of that happening in their backends, and they've demonstrated already that they're plenty capable of giving end users boxes the just so happen to do ipv6.

  Yes and setting up a single IPv4 VPS as load balancer with SNI routing in front of IPv6-only instances solves that. Most people are probably using ELB anyway

What do you mean not going to happen? It's already happening. It's about 45% of internet packets.

  Not happening for 55%. Try to connect to github.com over IPv6.

    It doesn't work now so it's never going to work?

      GitHub might work someday. Wide enough adoption that you can host a service without an IPv4 address will never happen.

        Honestly, it could be a feature rather than a bug…

      If it doesn't work for a website as large as technically forward as GitHub in 2024, the odds are not looking good.

    Yes, that's one of the rare exceptions of a company trying to obsolete itself. It's actually one reason a bunch of people are moving away from Github.
