Answer: B

Explanation:

The loopback address is a special IP address thatis designated for the software loopback interface of a computer. The loopback interface has no hardware associated with it, and it is not physically connected to a network. The loopback address causes any messages sent to it to be returned to the sendingsystem. The loopback address allows client software to communicate with server software on the same computer. Users specify the loopback address which will point back to the computer’s TCP/IP network configuration.

In IPv4, the loopback address is 127.0.0.1.

In IPv6, the loopback address is 0:0:0:0:0:0:0:1, which can be shortened to ::1
