> I have to admit, there is a learning curve. But I want to encourage everybody involved in configuring computers to learn. This is probably most of it. My gripe is that there is essentially no realistic end to ipv4 in sight. So we as an industry carry the debt of securing, managing and troubleshooting parallel v4 and v6 networks for decades. If ipv4 had an EOL it'd make the transition so much better

We have reached the point where it is feasible to run all new networks on IPv6 and treat IPv4 as legacy protocol on the edges and special devices. NAT64 works well enough for most IPv4 access. IPv6 network greatly simplifies networking. IPv4 will never go away, but will be smaller part of the Internet.

  It will probably be 20-30 years before it goes away. But I think there will be a point where service providers that drop v4 support in their networks. At that point clients that need v4 connectivity can use 4-in-6 tunneling/VPNs. It will absolutely hang around in small private networks for 50 years (there's still some token ring networks out there)

Nobody is in a position to EOL v4. We'd need a planetary government for that, and we don't have one. It would be nice, but we have to work with what we've got and not what we wish we had. I run my desktop with no v4, so it's clearly possible to push handling for v4 out of your network. You could outsource it to somebody else even, for example by using one of the DNS servers listed on https://nat64.net/ https://nat64.net/.

  We can EOL things insecure ciphers and old operating systems without much issue without a planetary government. The migration strategy for ipv4->ipv6 was just so horribly conceived that we'll be running both in parallel for decades. TBH I think it would have been better if ipv6 was named something else entirely. Running TCP and UDP in parallel doesn't raise any flags, but running two versions of the same protocol in parallel is strange.

    Can we? People continue to use both even after newer versions are released. I don't think it was horribly conceived. I think it's close to the best we can do given the constraints we're working under. These constraints include the fact that there are millions of networks being run by millions of people and nobody is in a position to force all of these people to stop using v4.

IPv4 will have a slow lingering death. We'll reach a steady state where everyone's running dual stack or IPv6 behind a v4 proxy/CG-NAT. Then as V4-only traffic drops content networks/application providers will start to drop support. That will drop the quality of the v4 internet, things will break and be slow to be fixed because who cares about the <10% v4 only traffic?
