[16:07] < jason> "Host hosting.realpractice.com not found: 3(NXDOMAIN)"
[16:07] < jason> Nope, somethings busted.
[16:08] < jason> One of your DNS servers has been updated with the right data, the other one not.
[16:11] < jason> Oh, huh.  Yeah, I'm getting different answeres from different places.
[16:11] < jason> Without researching it at all, I'm going to go ahead and blame IPv6.
[16:12] < neil> jason: which DNS server is outdated? or how did you find it? dig+whois not helpful
[16:13] < jason> I was using dig.  On a single box, I was getting correct resolution on one host but not on the other.
[16:14] < jason> But then testing the same NS from two different boxes, I was also getting different results.
[16:15] < jason> Possibly they're actually different NS's, doing unicast.
[16:15] < jason> Er, anycast.
