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?
Anton.
