> Why are we stuck with nat in 2022 again? Why did we not map the 32 bits of ipv4 to ipv6?

Because it does not help. djb's “idea” was to change everybody's setup _first_ and then have a flag day where the entire world were moved from IPv4 to IPv6 in one big change. Good luck with that. (And only after that flag day, we could start actually using a larger address space to try to get rid of NATs.)

The ipv6mess essay is confused because it somehow thinks _getting addresses_ is the hard problem. It does not solve _any_ other configuration or coding part. You still need to upgrade DNS. You still need to have a different wire protocol. You still need every hop on the path from me to you to understand and route IPv6.

At least now with gradual rollout and dual stack, we're at 40% of endpoints and AFAIK a majority of traffic. With djb's plan, we'd still be at zero.
