The main problem with IPv6 is that it is different from IPv4. There's SLAAC, there's no ARP and there're also some other differences. In the end, it's simpler to just not bother.

If IPv6 was going to be successful, it would have been successful years ago. It seems, people are just more comfortable with layers of NAT than native IPv6 everywhere. I'd guess that it should have been more backwards compatible. Similar to UTF-8 and ASCII.

IPv4 has been "in crisis" for the entire 20 years I've worked in tech and we seem to be managing alright. Not to say things can't be better or we shouldn't try to improve. But I'll be surprised if v4 isn't still the default for most use cases in another 20 years.

If UTF-8 represents the triumph of a design prioritizing backwards compatibility with an existing standard (ASCII) to facilitate a transition, then IPv6 is the cautionary tale of a design which could have made the transition simpler but did not.

I don’t know how you measure “metric tons of content” but I suspect in general there’s lots of US-available content on IPv4 that the countries like China and India want to access, and not much the other way around.

But that should be a perfect playground for an IPv6-only network that has gateways to the IPv4 content; eventually the home-developed content will begin to drive demand elsewhere.

“They’re out of IPs so they should self-genocide” is certainly something akin to an opinion, but not one I expected to see on this site today.
