NAME
     ethers - ethernet address to hostname database

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 blanks and/or tabs.  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, 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.
