I can't tell if this question is serious. It's either making fun of the
embarrassingly inadequate job we have done on this transition out it's
naive and ignorant in a genius way.

Read the asn32 migration docs for one that migrations like this can be
properly done.

This was harder but not impossible. We just chose badly for decades and now
we have NAT *and* a dumb migration.

Oh well.

That sounds like only using 6to4 addresses until the entire internet
supports IPv6.  Unfortunately there were NEVER enough IPv4 addresses
to actually do that.  We were effectively out of IPv4 addresses
before we started.

Add to that no one wanted to run 6to4 relays.  For the asn32 strategy
to work every IPv6 capable router needed to be a 6to4 relay and to
perform encapsulation / decapsulation depending upon whether the
next hop supported IPv6 or not.

we're stuck with that now (i wish i could say something about lessons
learned but i don't think any one of us has learned a lesson yet).

Would be really interesting to know how you would propose
squeezing 128 bits of address data into a 32 bit field so that we
could all continue to use IPv4 with more addresses than it's has
available to save having to move to this new incompatible format.
