In here we use php script just fellow the steps.

<?
//we have a variable  $ip_found that collect client ips
//this is for client server ips
if(!empty($_SERVER["HTTP_CLIENT_IP"]))
{

$ip_found = $_SERVER["HTTP_CLIENT_IP""];
}
//this is for client proxy ips
else if(!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))
{
$ip_found = $_SERVER["HTTP_X_FORWARDED_FOR"];

}
