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 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 character.  It is
      intended that host names in the ethers file correspond to the host names
      in the hosts(4) file.

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