       Validate::Net - Format validation for Net:: related strings


         use Validate::Net;

         my $good = '';
         my $bad = '123.432.21.12';

         foreach ( $good, $bad ) {
               if ( Validate::Net->ip( $_ ) ) {
                       print "'$_' is a valid ip\n";
               } else {
                       print "'$_' is not a valid ip address because:\n";
                       print Validate::Net->reason . "\n";

         my $checker = Validate::Net->new( 'fast' );
         unless ( $checker->host( '' ) ) {
               print "You provided an invalid host";


       Validate::Net is a class designed to assist with the validation of internet related
       strings. It can be used to validate CGI forms, internally by modules, and in any place
       where you want to check that an internet related string is valid before handing it off to
       a Net::* modules.

       It allows you to catch errors early, and with more detailed error messages than you are
       likely to get further down in the Net::* modules.

       Whenever a test is false, you can access the reason through the "reason" method.


   host $host
       The "host" method is used to see if a value is a valid host. That is, it is either a
       domain name, or an ip address.

   domain $domain [, @options ]
       The "domain" method is used to check for a valid domain name according to RFC 1034. It
       additionally disallows two consective dashes 'foo--bar'. I've never seen it used, and it's
       probably a mistaken version of 'foo-bar'.

       Depending on the options, additional checks may be made. No options are available at this

   ip $ip
       The "ip" method is used to validate the format, of an ip address.  If called with no
       options, it will just do a basic format check of the ip, checking that it conforms to the
       basic dotted quad format.

       Depending on the options, additional checks may be made. No options are available at this

   port $port
       The "port" method is used to test for a valid port number.




       This module is not all that completed. Just enough to do some basics. Feel free to send me
       patches to add anything you like.

       Add support for networks
       Add "exists" support
       Add "dns" support for host names
