publicsuffix 1.0.0

Get a public suffix for a domain name using the Public Suffix List.

This module allows you to get the public suffix of a domain name using the Public Suffix List from http://publicsuffix.org

A public suffix is one under which Internet users can directly register names. Some examples of public suffixes are .com, .co.uk and pvt.k12.wy.us. Accurately knowing the public suffix of a domain is useful when handling web browser cookies, highlighting the most important part of a domain name in a user interface or sorting URLs by web site.

Module content

The module exports a class that parses the Public Suffix List and allows queries for individual domain names:

>>> psl = PublicSuffixList()
>>> psl.get_public_suffix("www.example.com")
'example.com'

Please note that the host part of an URL can contain strings that are not plain DNS domain names (IP addresses, Punycode-encoded names, name in combination with a port number or an username, etc.). It is up to the caller to ensure only domain names are passed to the get_public_suffix() method.
