NAME
     ethers - Ethernet address to hostname database or domain

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

          Ethernet-address    official-host-name

     Items are separated by any number of SPACE and/or TAB  char-
     acters.   A `#' indicates the beginning of a comment extend-
     ing 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, represent-
     ing 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  character.   It  is
     intended  that  host  names in the ethers file correspond to
     the host names in the hosts(4) file.

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