Which is correct as you don't get an answer, you get a referral. The
resolver function is there for querying servers that have recursion
enabled. If you want to do other queries use the dns.query.udp function:
q = dns.message.make_query ('www.google.com.', dns.rdatatype.NS)
a = dns.query.udp (q, '192.228.79.201')
you can then traverse the additional section in a.additional.

I use the functions as described above to check if the zones on our
servers
are still delegated, so that should fit your purpose also.
Hope this helps.
