For IPv4 communications, the virtual loopback interface of a computer system is normally assigned the address '127.0.0.1' with subnetwork mask '255.0.0.0'. Depending on the specific operating system in use (notably in Linux), and the routing mechanisms installed, this often populates the routing table
of the local system with an entry so that packets destined to any
address from the '127.0.0.0/8' block would be routed internally to the
network loopback device.

In IPv6, on the other hand, the loopback routing prefix ::1/128 consists of only one address ::1
(i.e., 0:0:0:0:0:0:0:1, the address with a one at its least significant
bit and zero otherwise) is explicitly defined as an automatic loopback
address (RFC 3513), though additional addresses may be assigned to the loopback interface by the host administrator.
