NAME
hosts - The host name data base
SYNOPSIS
/etc/hosts
DESCRIPTION
The hosts file contains information regarding the known hosts on the
network. For each host a single line should be present with the following
information:
IP_address canonical_hostname aliases
Items are separated by any number of blanks and/or tab characters. The #
(number sign) indicates the beginning of a comment; characters up to the
end of the line are not interpreted by routines which search the file.
When using the name server named(8), this file provides a backup when the
name server is not running. For the name server, it is suggested that only
a few addresses be included in this file. These include address for the
local interfaces that ifconfig(8) needs at boot time and a few machines on
the local network.
This file may be created from the official host data base maintained at the
Network Information Control Center (NIC), though local changes may be
required to bring it up to date regarding unofficial aliases and/or unknown
hosts. As the data base maintained at NIC is incomplete, use of the name
server is recommend for sites on the DARPA Internet.
Network addresses are specified in the conventional . notation using the
inet_addr() routine from the Internet address manipulation library,
inet_addr(3). Host names may contain any printable character other than a
field delimiter, newline, or comment character.
