Description:
------------
if (Net_CheckIP::check_ip("226e+0.33.22.1")) {
echo "ok";
}

this returns "ok". but writing this addr into a postgresql database inet field returns an error.

Test script:
---------------
<?php
require_once "Net/CheckIP.php";

if (Net_CheckIP::check_ip("226e+0.33.22.1")) {
echo "ok";
} else {
echo "no";
}
?>

Instead of doing a is_numeric check on each octet, it will be better to do a is_int or a regex /^[0-9]+$/
or check the ip with this regx /^(\d+\.){3}\d+$/
