The name localhost is a commonly defined hostname for the loopback interface in most TCP/IP systems, resolving to the IP addresses 127.0.0.1 in IPv4 and ::1 for IPv6.As a top-level domain, the name has traditionally been defined statically in host DNS implementations with address records (A and AAAA) pointing to the same loopback addresses.
The hosts file is one of several system facilities that assists in addressing network nodes in a computer network. It is a common part of an operating system's Internet Protocol (IP) implementation, and serves the function of translating human-friendly hostnames into numeric protocol addresses, called IP addresses, that identify and locate a host in an IP network.
That means any packet sent to any of those addresses is looped back. The address 127.0.0.1 is the standard address for IPv4 loopback traffic; the rest are not supported by all operating systems. However, they can be used to set up multiple server applications on the host, all listening on the same port number.

For example, the loopback address 127.0.0.1 was commonly written as 127.1, given that it belongs to a class-A network with eight bits for the network mask and 24 bits for the host number. When fewer than four numbers were specified in the address in dotted notation, the last value was treated as an integer of as many bytes as are required to ...
Loopback (also written loop-back) is the routing of electronic signals or digital data streams back to their source without intentional processing or modification.It is primarily a means of testing the communications infrastructure.
At the same time, the releases began [9] to be PGP-signed. Afterwards, issue tracking moved to GitHub [ 10 ] and the mailing lists migrated. [ 11 ] Before version 4, which uses Ajax extensively to enhance usability, the software used HTML frames .
HTTP/2 is a revision of previous HTTP/1.1 in order to maintain the same client–server model and the same protocol methods but with these differences in order: to use a compressed binary representation of metadata (HTTP headers) instead of a textual one, so that headers require much less space;
