NAME

Mozilla::PublicSuffix - Get a domain name's public suffix via the Mozilla Public Suffix List

SYNOPSIS

    use feature "say";
    use Mozilla::PublicSuffix "public_suffix";

    say public_suffix("org");       # "org"
    say public_suffix("perl.org");  # "org"
    say public_suffix("perl.orc");  # undef
    say public_suffix("ga.gov.au"); # "gov.au"
    say public_suffix("ga.goo.au"); # undef

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 As the official list continues to be updated, the bundled copy will inevitably fall out of date. Therefore, if the bundled copy of found to be over thirty days old, this distribution's installer provides the option 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 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.
