       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 for-

       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
