alt Hacker News> Just like with IPv6.
Yes, but the compatibility is very very easy to support for both hardware vendors, softwares, sysadmins etc. Some things might need a gentle stroke (mostly just enlarge a single bitfield) but after that everything just works, hardware, software, websites, operators.
A protocol is a social problem, and ipv6 fails exactly there.

I'm confused by the argument that replacing equipment is something that is always possible. It doesn't matter that it's easy to support by updating or replacing the hardware - a lot of hardware isn't going to be updated or replaced.

What slowed ipv6 wasn’t the design of ipv6, it was the invention of NAT and CGNAT.
Even still. The rollout is still progressing, and new systems like Matter are IPv6 only.
