Thanks Jean-Paul, I tried changing to queryUDP, and it just sits there, never sends out a query (watching with tcpdump). If I change it to _lookup, which it looks like queryUDP calls, it sends the query, but like lookupAddress, I don't get the additional and auth sections still... What is weird, when I do this deferred = resolver.queryUDP([Dns.Query(name, dns.IN, dns.A)]) and I try and debug why it's hanging, I put a print in the ResolverBase.queryUDP function right at the top, and it never prints.

Hey all,
I have a client I have written using twisted.names that will send a DNS request. Here is the gist of the relevant code:
(tfp, tfile) = tempfile.mkstemp() os.write(tfp, 'nameserver %s' % ip) os.close(tfp) resolver = client.createResolver(resolvconf=tfile) deferred = resolver.lookupAddress(somevalue) deferred.addCallback(resultHandler)
hacky way to set the IP, but I am having issues with passing in the "servers" list I don't want to troubleshoot until I figure out this problem.
Anyways, as you can see, this code calls the lookupAddress method for the name I want. The problem I am having is it is only returning the answer section of the response. I need the additional and authority sections as well (and I know for sure those sections exist in the response). I have looked at the docs and the code, and I don't know what I am missing. I am sure it's something silly, but I am missing it right now.
So long question short, what do I need to change in my code so I can get the additional sections and authority sections in the response so I can get to those values?
One approach would be to use queryUDP directly instead of lookupAddress:
resolver.queryUDP([dns.Query(name, dns.A, dns.IN)])
Which will give you a full message object back, including lists of answers, additional, and authority sections.
