.TH HOSTS 5
 | 
						|
.SH NAME
 | 
						|
hosts \- hostname to IP address database
 | 
						|
.SH SYNOPSIS
 | 
						|
.B /etc/hosts
 | 
						|
.SH DESCRIPTION
 | 
						|
The hosts database lists the IP addresses and the hostnames that translate
 | 
						|
to these IP addresses.  It is used by
 | 
						|
.BR nonamed (8)
 | 
						|
in a network without name servers.  A simple
 | 
						|
.B /etc/hosts
 | 
						|
may look like this:
 | 
						|
.PP
 | 
						|
.RS
 | 
						|
.ta +15n
 | 
						|
.nf
 | 
						|
10.0.0.1	flotsam
 | 
						|
10.0.0.2	jetsam
 | 
						|
.fi
 | 
						|
.RE
 | 
						|
.PP
 | 
						|
These two entries give names to two IP addresses.  The file may contain
 | 
						|
comments marked with '#'.
 | 
						|
.PP
 | 
						|
You can have aliases (more hostnames on the same line) to give a machine
 | 
						|
more than one name, like
 | 
						|
.BR www ,
 | 
						|
if you run a web server on one.
 | 
						|
.PP
 | 
						|
If your PC is Internet connected then you can specify the name server(s)
 | 
						|
to get more information from with %nameserver entries:
 | 
						|
.PP
 | 
						|
.RS
 | 
						|
.ta +\w'172.16.24.3'u+4m +\w'%nameserver'u+4m
 | 
						|
.nf
 | 
						|
172.16.24.3	%nameserver	# dns1.example.com
 | 
						|
172.16.24.6	%nameserver	# dns2.example.com
 | 
						|

Read
 | 
						|
.BR nonamed (8)
 |

for all the details on special host file entries that configure
 | 
						|
.B nonamed
 | 
						|
for use on the Internet, and on home machines that are occasionally
 | 
						|
connected to the Internet.
