Ethernet Numbers


                      ETHERNET NUMBERS OF INTEREST

   Many of the networks of all classes are Ethernets (10Mb) or
   Experimental Ethernets (3Mb).  These systems use a message "type"
   field in much the same way the ARPANET uses the "link" field.

   If you need an Ethernet number, contact the XEROX Corporation, Office
   Products Division, Network Systems Administration Office, 333 Coyote
   Hill Road, Palo Alto, California, 94304.
