       List

SYNOPSIS

           use feature qw(say);
           use Mozilla::PublicSuffix qw(public_suffix);

           say public_suffix('org');       # 'org'

DESCRIPTION

       This module provides a single function that returns the public suffix of a domain name by
       referencing a parsed copy of Mozilla's Public Suffix List.  From the official website at
       <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. The Public Suffix List
           is a list of all known public suffixes.

       A copy of the official list is bundled with the distribution. As the official list
       continues to be updated, the bundled copy will inevitably fall out of date.  Aside from
       new releases always including the latest version of the list, this distribution's
       installer provides the option (defaults to "No") to check for a new version of the list
       and download/use it if one is found.

FUNCTIONS

       public_suffix($domain)
           Exported on request. Simply returns the public suffix of the passed domain name, or
           "undef" if either the domain name is not well-formed or the public suffix is not
           found.

SEE ALSO

       Domain::PublicSuffix
           Similar to this module, with an object-oriented interface and somewhat alternative
           interpretation of the rules Mozilla stipulates for determining a public suffix.

       IO::Socket::SSL::PublicSuffix
           Ships with "IO::Socket::SSL", used by many HTTP client libraries for SSL/TLS support,
           and makes it easy to use the current version of the public suffix list at run-time.
