'k, I just did a major overhaul of our DNS this month ... 200.46.204.2 was
getting overloaded, and there was no easy way to move things around, so I
put the DNS servers on a floating IP (the IP doesn't change, it can just
float between servers) instead of tying it to a specific server ...
So, the IPs should all be:
?column? | data
-------------+----------------
ns4.hub.org | 200.46.208.251
ns.hub.org | 200.46.204.13
ns2.hub.org | 66.98.250.36
ns3.hub.org | 200.46.204.254
(4 rows)
Everything is in a bind-dlz database right now (except postgresql.org
itself, since I haven't quite figured out a clean way of doing that yet,
since its generated based on other data sources) ...
Primaary is 200.46.204.13, as the others are all slony slaves from it ...
