Because it gave you the IP of ns1 & ns2.push.mobi in the additional section? Looks like a pretty normal answer for a TLD server.

It gives me the list of dot mobi authorized name servers. I'm expecting it to be answered by one of the mobi tld authorized name servers, but it's telling me that it delegates the answer to ns1.push.mobi instead. It does not make sense for me because how can I ask ns1.push.mobi if I don't know its ip address yet... Clue please..? ----- az@hollywood:~$ dig @B2.MOBI.AFILIAS-NST.ORG. ns1.push.mobi .... ;; QUESTION SECTION: ;ns1.push.mobi.
