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