       ethers - Ethernet address to hostname database or domain

       The  ethers  file  is  a local source of information about the (48-bit)
       Ethernet addresses of hosts on the Internet. The  ethers  file  can  be
       used  in conjunction with or instead of other ethers sources, including
       the NIS maps ethers.byname and ethers.byaddr, the NIS+ table ethers, or
       Ethernet  address  data  stored  on  an  LDAP  server. Programs use the
       ethers(3SOCKET) routines to access this information.

       The ethers file has one line for each host on an Ethernet. The line has
       the following format:

              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 SPACE, TAB, NEWLINE, or comment character.
