HOSTS(5)		      File Formats Manual		      HOSTS(5)

NAME
       hosts --	host name data base

DESCRIPTION
       The  hosts  file	 contains information regarding	the known hosts	on the
       network.	 It can	be used	in conjunction with  DNS,  and	the  NIS  maps
       `hosts.byaddr'  and  `hosts.byname', as controlled by nsswitch.conf(5).
       For each	host a single line should be present with the following	infor-
       mation:

	     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.

       This  file  provides a backup used when the name	server is not running.
       For the name server, it is suggested that only a	few addresses  be  in-
       cluded  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.

       Network	addresses are specified	in either the conventional ``.'' (dot)
       notation	for IPv4 or colon hexadecimal notation for IPv6, as understood
       by the inet_pton(3) routine from	the Internet address manipulation  li-
       brary,  inet(3).	  Host names may contain any printable character other
       than a field delimiter, newline,	or comment character.

FILES
       /etc/hosts  The hosts file resides in /etc.
