Class networks
Net_CheckIP2 has a getClass method which helps the developer to determine if the IP is within an class A, B or C network.
In case getClass is unable to determine the class, or the IP is invalid, false is returned.
getClass
<?php
require_once 'Net/CheckIP.php';
$ip = '127.0.0.1';
$classNetwork = Net_CheckIP::getClass($ip);
if ($classNetwork === false) {
die('Unable to determine the class. The IP might be invalid also.');
}
switch ($classNetwork) {
case Net_CheckIP2::CLASS_A:
echo 'Class A network.';
break;
case Net_CheckIP2::CLASS_B:
echo 'Class B network.';
break;
case Net_CheckIP2::CLASS_C:
echo 'Class C network.';
break;
}
?>
