Everyone has effectively IPv6-only customers today. IPv6 native +
CGN only works for services. Similarly DS-Lite and 464XLAT.
Sometimes you can get away w/o IPv6, sometimes you can't. In all
cases IPv4 is getting more and more expensive to support as more
customers share public IP addresses even if it is just have to
re-tune rate limits to account for the sharing.
