[lug] Weird DNS problems

[Chip Atkinson]

I believe that jymis.com has the authoritative domain records.  That 
what dig seems to indicate:

;; AUTHORITY SECTION:
pupman.com.             16h25m42s IN NS  ns1.jymis.com.
pupman.com.             16h25m42s IN NS  ns0.jymis.com.

AAARGHHH!!! Ok, I think this is the problem:

 > server G.GTLD-SERVERS.NET
Default Server:  G.GTLD-SERVERS.NET
Address:  192.42.93.30

 > pupman.com
Server:  G.GTLD-SERVERS.NET
Address:  192.42.93.30

Non-authoritative answer:
Name:    pupman.com
Address:  199.45.150.249

(The 199.45... address is old and out of date)  It should be 63.173.117.115.

Ok, how did you resolve the problem?

Thanks for the advice.
