Hi.

The main objective for today is to access the web services, that's why you
can't reach a AAAA record for a DNS query for a given NS server.

You see? there's a lot of IPv6 activity since a few weeks ago. xD

Subject: AAAA on various websites, but they all forgot to enable them

It is really nice that folks where able to put AAAA records on their
websites for only 24 hours, but they forgot to put in the glue on their
nameservers.

As such, for the folks testing IPv6-only, a lot of sites will fail
unless they use a recursor that does the IPv4 for them.

The root is there, .com does it mostly too (well, a+b have IPv6), but
most sites don't. Thus maybe that can be done next year on the next IPv6
day? :)

At least one step closer, now lets hope that sites also keep that IPv6
address there.

Greets,
 Jeroen
