hosts(4) Kernel Interfaces Manual hosts(4)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 fol-
lowing 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 incom-
plete, 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.

networks - network name data base
DESCRIPTION
The networks file contains information regarding the known networks which comprise the DARPA Internet. For each network a single line
should be present with the following information:
official network name
network number
aliases
Items are separated by any number of blanks and/or tab characters. A ``#'' indicates the beginning of a comment; characters up to the end
of the line are not interpreted by routines which search the file. This file is normally created from the official network data base main-
tained 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 networks.
Network number may be specified in the conventional ``.'' notation using the inet_network() routine from the Internet address manipulation
library, inet(3N). Network names may contain any printable character other than a field delimiter, newline, or comment character.
