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.	 For each host a single	line should be present with  the  fol-
       lowing 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  used
       when  the  name server is not running.  For the name server, it is sug-
       gested that only	a few addresses	be included in this file.   These  in-
       clude 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), 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 recommended for sites on the DARPA	Internet.

       Network addresses are specified in the conventional ``.''  (dot)	 nota-
       tion using the inet_addr(3) routine from	the Internet address manipula-
       tion  library, 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.
