DESCRIPTION

This module uses the list of effective top level domain names from the mozilla project to determine the public top level domain for a given hostname.

Method

class->default(%args)
Returns object with builtin default. min_suffix can be given in %args to specify the minimal suffix, default is 1.

class->from_string(string,%args)
Returns object with configuration from string. See method default for %args.

class->from_file( file name| file handle, %args )
Returns object with configuration from file or file handle. See method default for %args.

$self->public_suffix( $host|\host, [ $add ] )
In array context the function returns the non-tld part and the tld part of the given hostname, in scalar context only the tld part. It adds $add parts of the non-tld part to the tld, e.g. with $add=1 it will return the root domain. If there were no explicit matches against the public suffix configuration it will fall back to a suffix of length 1. The function accepts a string or an array-ref (e.g. host split by .). In the first case it will return string(s), in the latter case array-ref(s). International hostnames or labels can be in ASCII (IDNA form starting with xn--) or unicode. In the latter case an IDNA handling library needs to be available. URI is preferred, but Net::IDN:::Encode, Net::LibIDN are still supported.

($self|class)->can_idn
Returns true if IDN support is available.

BUGS

Q: Why yet another module, we already have L<Domain::PublicSuffix> and L<Mozilla::PublicSuffix>. A: Because the public suffix data change more often than these modules do, IO::Socket::SSL needs this list and it is more easy this way to keep it up-to-date.
