IPv6 Routes in L3

Thu Feb 21 03:39:05 UTC 2013

Anyone have visibility on Level 3 IPv6 routing? I'm unable to reach
http://fedoraproject.org by their primary and ended up having to spoof a
secondary in local DNS. Note that this is on HughesNet; multiple levels of
support have been clueless or stumped.

For the curious:

[darton at dkw-vostro ~]$ dig -6 @google-public-dns-a.google.com -t aaaa
www.fedoraproject.org

; <<>> DiG 9.9.2-P1-RedHat-9.9.2-3.P1.fc17 <<>> -6 @
google-public-dns-a.google.com -t aaaa www.fedoraproject.org

Love the beefy theme there...

fed2 is the only one I can't reach, and though the AAAA records are
round-robin, fed2 appears to be the one to which HTTP requests get routed
and tracing that takes me from Salt Lake to Munich by way of Paris before
timing out:

fed4 is a different route:

Any ideas/comparisons/insights appreciated. This is so far the only native
IPv6 connection I have, despite having access to two datacenters and FiOS,
so not much to compare it with. Shameful.

...Yeah, that guy.
