Fedora IPv6 testing and improvements - request for ideas

[Toby Goodwin]

As well as Fedora itself, we need to get the infrastructure IPv6 ready.
My company has developed an IPv6 health checker. Given a domain, it
tests its nameservers, webservers, and mailservers for IPv6 readiness.

Currently fedoraproject.org scores 4 out of 9, so there's some room for
improvement!

It seems odd that there are AAAA records for ns0[25], but they point to
"dead:beef" addresses that are unreachable. Is this deliberate? Seems
like it will just slow things down for any resolver that happens to
try the IPv6 address first. (And of course the domain is completely
unresolvable from a "pure" IPv6 client.)
