I have strong opinions about ipv4, especially since I'm forced to use an ipv4 isp. The lack of ipv6 adoption should be considered one of the great failures of tech. Who actually is responsible? Is it router manufacturers writing poor quality firmware, ipv4 advocates in leadership positions at isps, ipv4 address speculators, poor training of network engineers and tech support staff? I think we all need to have a much greater discussion with the internet at large and not just on isolated web posts and subreddits.

For comparison, the internet mostly transitioned off of TLS 1.0 just fine, why can't we do the same for transitioning off ipv4? Maybe AI powered proxies for legacy code perhaps?

The difference is only the end client and server need to support TLS, all the middleware and networks between just see TCP packets and do not have to be privy to what TLS version is being used.

IPv6 on the other hand has to be supported by every middleware box between the client and the server and therefore its functionality is limited by the lowest common denominator.

Additionally TLS upgrades were largely drop in, whereas IPv6 changed too many things at once to be easily adopted.

Hindsight is 20/20, but I firmly believe that IPv6 should have only changed source and destination addresses to be 64 bits and that was the entire RFC.
