[arin-ppml] IPv6 in the Economist

I'm unsure why you think IPv6 is broken simply because the DNS
infrastructure isn't completely rolled out yet or is designed in a
fashion not to your liking.

This will take some time, but is hardly holding up deployment.

I see no reason why there is a problem mixing IPv4 and IPv6 addresses in
DNS. DNS is just a database, it contains a lot of other non ip address
records like SPF and DKIM, TXT.. So putting both IPv4 and IPv6 addresses
into the same nameserver is quite reasonable. How you access the
nameserver, either via IPv4, IPv6 or X.25 even, isn't the question.

huh? I don't understand your point.
The fact is. IPv4 isn't going away for a very long time. The *only*
reasonable rollout involves dual stack existing for a long time.
Separating transport from content (be it web, dns records, anything) and
making it accessible from both IPv4 and v6 is going to be the norm, for
a long time.
Owing to the nature of dual stack, I don't think anyone is in a hurry to
roll out end-to-end IPv6-only deployments. Our first goal should be to
get IPv6 networks and routing rolled out to our IPv4 customers so
dual-stack will even have a chance of working.
