Hi,

Why not approach this with plain strings?

$ip = SERVER['REMOTE_ADDR'];
$allowIP = array('123.123.123.12' , '123.123.123.115');

$passOK = 'Y';
if (substr($ip,0,7) == '123.123'){
// not welcome, unless in $allowIP
if (in_array($ip,$allowIP)){
$passOK = 'Y';
} else {
$passOK = 'N';
}
}

If you need more complex fitting of IP-addresses than just simple
'startstring-fitting', you'll need more complex code of course.
