Quizplus · Accepted Answer

Use the ping 127.0.0.1 command to perform the loopback test. This test should be performed locally on the computer.
Key Takeaway: The loopback address sends outgoing signals back to the same computer for testing. In a TCP/IP network the loopback IP address is always 127.0.0.1 and pinging it will return a reply. The loopback address allows a network administrator to treat the local machine as if it were a remote machine.
