I always cringe when folks say premium internet.  Internet is always "best
effort", we are all always reduced to the least common denominator for
network quality.

I would say networks that only have ipv4 are not doing their best effort.
There will not be suitable truly ipv6-only offering in the next 10 Years
because of these laggards.

That said, buying ipv4 makes me feel ill. Please put ipv4 where it belong
in the cgn / nat64 / MAP br / aftr.

Ipv4 is not premium, it is legacy services deployed by companies on a
downward slide. . My customers care about fb and google and netflix, those
are top services and all on ipv6
