Explanation:
Section Reference: Defining a LAN
You can ping your own computer using the loopback address, also known as the local loopback. When pinging
this address, no network traffic is incurred; because the network adapter is really just looping the ping back to
the OS, it never places any packets on to the network. Therefore, this is a solid way to test whether TCP/IP is
installed correctly to a network adapter, even if y ou arent physically connected to a network.
