routing, which can be used to specify a direct path between a source address and a destination address. For some TCP and UDP services, the IP packet that uses the option is passed over from the last system on the path, not from its real location. This option exists for testing purposes, indicating that it can be used to spoof the system for normally blocked connections. Then, many services that rely on the
