ETHERS(5)		      File Formats Manual		     ETHERS(5)

NAME
       ethers -	Ethernet address to hostname database or NIS domain

DESCRIPTION
       The  ethers file	contains information regarding the known (48 bit) Eth-
       ernet addresses of hosts	on the Internet.  For each host	on  an	Ether-
       net, a single line should be present with the following information:

	      Ethernet-address	  official-host-name

       Items  are  separated by	any number of blanks and/or TAB	characters.  A
       `#' indicates the beginning of a	comment	extending to the end of	line.

       The standard form for Ethernet addresses	is ``x:x:x:x:x:x'' where x  is
       a  hexadecimal  number  between	0  and ff, representing	one byte.  The
       address bytes are always	in network order.  Host	names may contain  any
       printable  character other than a SPACE,	TAB, NEWLINE, or comment char-
       acter.  It is intended that host	names in the ethers file correspond to
       the host	names in the hosts(5) file.

       The   ether_line()  routine  from  the  Ethernet	 address  manipulation
       library,	ethers(3N) may be used to scan lines of	the ethers file.

FILES

NOTES
       The Network Information Service (NIS) was formerly known	as Sun	Yellow
       Pages  (YP).   The  functionality of the	two remains the	same; only the
       name has	changed.
