HOSTS(5)		  FreeBSD File Formats Manual		      HOSTS(5)

     hosts -- host name	data base

     The hosts file contains information regarding the known hosts on the net-
     work.  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 informa-

	   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.

     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 net-

     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), nsswitch.conf(5), ifconfig(8)

     The hosts file format appeared in 4.2BSD.
