Extracting real-domain-name (without sub-domains) from a given URL

[S.Selvam Siva]

Hi all,

  I need to extract the domain-name from a given url(without sub-domains).
With urlparse, i am able to fetch only the domain-name(which includes the
sub-domain also).

eg:
  http://feeds.huffingtonpost.com/posts/ , http://www.huffingtonpost.de/,
.... all must lead to *huffingtonpost.com or huffingtonpost.de**
*
Please suggest me some ideas regarding this problem.
