  Ethernet address
       
           (Or "{MAC address") The physical address
          identifying an individual Ethernet controller board.  An
          Ethernet addess is a 48-bit number aabbccddeeff where a-f are
          hexadecimal digits.  The first 24 bits, aabbcc, identify the
          manufacturer of the controller.  The Ethernet address is
          hard-wired on some controllers, stored in a ROM on some, and
          others allow it to be changed from software.  It is usually
          written as six hexadecimal numbers, e.g. 08:00:20:03:72:DC.
