  dnspython provides both high and low level access to DNS. The high level 
  classes perform queries for data of a given name, type, and class, and 
  return an answer set. The low level classes allow direct manipulation of 
  DNS zones, messages, names, and records.
...
  dnspython is a utility to work with DNS, /etc/hosts is thus not used. 
  For simple forward DNS lookups, it's better to use socket.getaddrinfo() 
  or socket.gethostbyname().

  dnspython originated at Nominum where it was developed to facilitate the 
  testing of DNS software.
