Hi monks,

I work with a database that stores a pool of IP addresses in numeric form. If any of you have to deal with something similar, here's a handy little function that can convert IP addresses into numeric form. 

sub ipToNum {
        my $ip = shift;
        my @octets  = split(/\./, $ip);
        my $ip_number = 0;
        foreach my $octet (@octets) {
                $ip_number <<= 8;
                $ip_number |= $octet;
        }

        return $ip_number;

}

So, for example, if you feed it 192.168.0.1, it will return 3232235521.
