NAME
    Net::IPAddress::Minimal - IP string to number and back

VERSION
    Version 0.01

SYNOPSIS
    This module converts IPv4 strings to integer IP numbers and vice versa.

    It's built to be used as quickly and easily as possible, which is why
    you can just simply use the invert_ip function.

    It recognizes whether you have an IPv4 string or a number and converts
    it to the other form.

    Here's a sample script:

    ` use strict; use warnings;

        use Net::IPAddress::Minimal ('invert_ip');

        my $input_string = shift @ARGV;

        my $output = invert_ip( $input_string );

        print "$output\n";
    `

EXPORT
    Three functions can be exported:

    invert_ip num_to_ip ip_to_num

SUBROUTINES/METHODS
  invert_ip
gets an IPv4 string or an IP number and converts it to the other form.
    ` my $ip_num = invert_ip( '10.200.10.130' ); # $ip_str = 180882050

        my $ip_num = invert_ip( 180882050 );
        #  $ip_str  = '10.200.10.130';
    `

  num_to_ip
    Gets an IP number and returns an IPv4 string.

        my $ip_num = num_to_ip( 3232235778 );
        #  $ip_str  = '192.168.1.2';

  ip_to_num
    Gets a IPv4 string and returns the matching IP number.

    ** Note that at the moment this function does not ensure that each of
    the class numbers are between 0-255, and it can return unexpected
    results when misused **

        my $ip_arrayref = '212.212.212.212';
        my $ip_num      = ip_to_num( $ip_arrayref );
        #  $ip_num      = 3570717908

  test_string_structure
    Checks the structure of the input string and returns flags indicating
    whether it's an IPv4 string, and IP number or something else (which is
    an error).
