# Host name database.
#
# This file contains addresses and aliases for local hosts whose names
# need to be resolvable during system boot; typically this includes only
# the address and FQDN for this machine's hostname.
#
# By default this file is consulted before DNS, so adding additional
# material here that then becomes out of date can lead to confusion.
# See nsswitch.conf(5).

::1 localhost localhost.
127.0.0.1 localhost localhost.
#
# RFC 1918 specifies that these networks are "internal":
# 10.0.0.0 - 10.255.255.255 (10/8 prefix)
# 172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
# 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

.Sh NAME
.Nm hosts
.Nd host name data base
.Sh DESCRIPTION
The
.Nm hosts
file contains information regarding the known hosts on the network.
It can be used in conjunction with the DNS, and the
.Tn NIS
maps
.Sq hosts.byaddr ,
and
.Sq hosts.byname ,
as controlled by
.Xr nsswitch.conf 5 .
.Pp
For each host a single line should be present
with the following information:
.Dl address hostname [alias ...]
.Pp
These are:
.Bl -tag -width hostname -compact -offset indent
.It Em address
Internet address
.It Em hostname
Official host name
.It Em alias
Alias host name
.El
.Pp
Items are separated by any number of blanks and/or
tab characters. A hash sign
.Pq Dq \&#
indicates the beginning of
a comment; characters up to the end of the line are
not interpreted by routines which search the file.
.Pp
When using the name server
.Xr named 8 ,
or
.Xr ypserv 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
.Xr ifconfig 8
needs at boot time and a few machines on the local network.
.Pp
This file may be created from the official host
data base maintained at the Network Information Control
Center
.Pq Tn 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
.Tn NIC
is incomplete, use of the name server is recommended for
sites on the
.Tn DARPA
Internet.
.Pp
As network addresses, both IPv4 and IPv6 addresses are allowed.
IPv4 addresses are specified in the conventional dot
.Pq Dq \&.
notation using the
.Xr inet_pton 3
routine
from the Internet address manipulation library,
.Xr inet 3 .
IPv6 addresses are specified in the standard hex-and-colon notation.
Host names may contain any printable
character other than a field delimiter, newline,
or comment character.
