* ip_in_range.php - Function to determine if an IP is located in a
* specific range as specified via several alternative

*
* Network ranges can be specified as:
* 1. Wildcard format: 1.2.3.*
* 2. CIDR format: 1.2.3/24 OR 1.2.3.4/255.255.255.0
* 3. Start-End IP format: 1.2.3.0-1.2.3.255
*
* Return value BOOLEAN : ip_in_range($ip, $range);
