NAME ^

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

SYNOPSIS ^

  use Validate::Net;

  my $good = '123.1.23.123';
  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( 'foo.bar.blah' ) ) {
        print "You provided an invalid host";
  }

DESCRIPTION ^

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.

METHODS ^

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 time

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 time

port $port

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

BUGS ^

Unknown
