You could try converting to long IP addresses and comparing that way:

<?php

// To actually get the long IP address that you can use in http://
// you sometimes need to use something like printf("%u\n", ip2long($ip));

// See also: http://us3.php.net/manual/en/function.ip2long.php

$startip = "192.168.0.5";
$endip = "192.168.0.16";
$targetip = "192.168.0.7";

$startlong = ip2long($startip);
$endlong = ip2long($endip);
$targetlong = ip2long($targetip);

if ($startlong <= $targetlong AND $targetlong <= $endlong)
echo "within range";
else
echo "out of range";


?>

Does anyone have a function that will check if an ip address falls with
a starting/ending ip address range>>



Thanks,
