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