NAME
hosts - host name data base
DESCRIPTION
The file associates Internet (IP) addresses with official host names and aliases. This allows a user to refer to a host by a symbolic name
instead of an Internet address.
This file contain all addresses for local interfaces that needs at boot time (see ifconfig(1M)). When using the name server (see
named(1M)), or Network Information Service (see ypserv(1M)), this file often serves as a backup when the server is not running. In such
circumstances, it is a common practice for to contain a few addresses of machines on the local network.
should contain a single line for each host with the following information:
internet_address official_host_name aliases
The internet_address can be an IPv4 or IPv6 address specified in the conventional Internet dot notation. See inet(3N) or inet6(3N) for
more information on Internet address manipulation routines.
aliases are other names by which a host is known. They can substitute for the official_host_name in most commands. For example:
In this example, users can use remote login on by using the command:
instead of
If your system is in a domain naming environment, an official host name consists of the full domain extended host name. For example:
(space or tab character). Items are separated by any number or combination of space or tab characters (blanks). A character indicates the
beginning of a comment. Characters from the to the end of the line are not interpreted by routines that search the file. Trailing blanks
are allowed at the end of a line.
For the Internet, this file is normally created from the official host database maintained at the Network Information Control Center (NIC),
although local changes may be required to bring it up to date with respect to unofficial aliases and/or unknown hosts.
Host names can contain any printable character other than a white space, newline, or comment character.
