HOSTS(5)		    BSD	File Formats Manual		      HOSTS(5)

     hosts -- host name	data base

     The hosts file contains information regarding the known hosts on the net-
     work.  For	each host a single line	should be present with the following

	   Internet address
	   official host name

     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 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), though local	changes	may be
     required to bring it up to	date regarding unofficial aliases and/or un-
     known 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) notation
     using the inet_addr(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.

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

     gethostbyname(3), ifconfig(8), named(8)

     Name Server Operations Guide for BIND.

     The hosts file format appeared in 4.2BSD.
