Loopback

routing of signals back to their source without intentional processing or modification

The loopback address[1] is a computing term that is a special IP address of a computer's ethernet network. It is used to allow software on a computer to send information to the same computer using the TCP/IP stack. The special IP address is known as 127.0.0.1 (IPv4) or 0:0:0:0:0:0:0:1 (::1, IPv6).[2]
