Yes, bit basic but it should work. substr(). www.php.net/substr $FirstPartIp = substr($ip,0,5); if($FirstPartIp=='10.8.4' || $FirstPartIp=='10.8.5'){ echo 'We have a local IP, continue!'; }else{ echo 'Get out stupid hacker';} Should work. An other way is exploding the IP by . www.php.net/explode $IpParts = explode('.',$ip); $IpParts is now an array and you can check for the correct address.
