I did see the info from additional section, but:

Afaik the additional section is not an answer, they're just additional
info, not an authorized answer from the queried name server. I'm
expecting to get a reply for my 'A' query in the 'answer section'.

Now, from the 'authority section' dig is telling me that I can get the
authorize answer from ns1.push.mobi. But isn't that circular
dependency?

Hi,
I'm looking for glue record for ns1.push.mobi so I ask one of the root
name 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..?
