title: dnsPython - answer from dns.resolver.query
body: <p>I need some help with getting nameserver (NS) records from specific domains.
  So far i had no problem with my script but now I realised that it has
  problem getting answer from domains like this: fpv.ukf.sk
  With simple domain like google.com, ukf.sk etc. I have no problem. </p>
  
  <p>used code:
  answers = dns.resolver.query('fpv.ukf.sk', 'NS')</p>
  
  <p>I get this error:
      answers = dns.resolver.query('fpv.ukf.sk', 'NS')
    File "build\bdist.win32\egg\dns\resolver.py", line 920, in query
      raise_on_no_answer, source_port)
    File "build\bdist.win32\egg\dns\resolver.py", line 858, in query
      raise_on_no_answer)
    File "build\bdist.win32\egg\dns\resolver.py", line 133, in <strong>init</strong>
      raise NoAnswer
