file hosts is an operating system file that maps hostnames to
IP address. It is a plain
text file. Originally a file named HOSTS.TXT was manually maintained and made available via file sharing by Stanford
Research Institute for the Arpanet membership, containing the
hostnames and address of hosts as contributed for inclusion by member organizations. The Domain
name system, first described in 1983 and implemented in 1984, automated
the publication process and provided instantaneous and dynamic hostname resolution in the rapidly growing network. In modern operating systems, the hosts file remains an alternative name resolution mechanism, configurable often as part of facilities such as
the Name service switch as either the primary method or as a fallback method.
