NAME
hosts - host name data base
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:
Internet address
official host name
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.
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 addresses 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)
(see
"FYI on Where to Start - A Bibliography of
Internetworking
Information" (RFC1175) in the MachTen System &
Network
Administration manual), 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(3). Host names may contain any
printable character other than a field delimiter, newline,
or
comment character.
