Net::Domain::TLD - Work with TLD names 

  use Net::Domain::TLD qw(tlds tld_exists);
  my @ccTLDs = tlds('cc');
  print "TLD ok\n" if tld_exists('ac','cc');

  The purpose of this module is to provide user with current list of 
  available top level domain names including new ICANN additions and ccTLDs
  Currently TLD definitions have been acquired from the following sources:

  http://www.icann.org/tlds/
  http://www.dnso.org/constituency/gtld/gtld.html
  http://www.iana.org/cctld/cctld-whois.htm

  Each public function/method is described here.
  These are how you should interact with this module.

  This routine returns the tlds requested.

  my @all_tlds = tlds; #array of tlds
  my $all_tlds = tlds; #hashref of tlds and their descriptions

  my @cc_tlds = tlds('cc'); #array of just 'cc' type tlds
  my $cc_tlds = tlds('cc'); #hashref of just 'cc' type tlds and their descriptions

  Valid types are:
    cc                 - country code domains
    gtld_open          - generic domains that anyone can register
    gtld_restricted    - generic restricted registration domains
    new_open           - recently added generic domains
    new_restricted     - new restricted registration domains

  This routine returns true if the given domain exists and false otherwise.

  die "no such domain" unless tld_exists($tld); #call without tld type 
  die "no such domain" unless tld_exists($tld, 'new_open'); #call with tld type
