Attached is the most recent list of Ethernet Type Fields, Vendor Addresses, and known Multicast Addresses. please send comments or additions directly to Urbaniak@BBN.COM. Future publications of this information will probably be as a TCP/IP Internet RFC, rather than email to this mailing list. If you wish to comment on the format in which this data should be presented, or if you wish to be placed on a private mailing list for these updates, please send me mail at Urbaniak@BBN.COM, or US Mail at Bolt, Beranek & Newman, Inc. 10 Fawcett Street Cambridge, MA 02138 attn: Walter Urbaniak, MS021 Some Known Ethernet and IEEE802.3 "Type" Fields 3/16/89 The 13th and 14th octets of an Ethernet or IEEE802.3 packet (after the preamble) consist of the "Type" or "Length" field. These values are managed by XEROX. Some assignments are public, others private. Current information includes: Xerox Public Ethernet Packet Type documentation; IEEE802.3 Std; NIC RFC960; contributions from network managers and vendors.

These 12 hex digits consist of the first/left 6 digits (which should match the vendor of the Ethernet interface within the station) and the last/right 6 digits which specify the interface serial number for that interface vendor. Ethernet addresses might be written unhyphenated (e.g. 123456789ABC), or with one hyphen (e.g. 123456-789ABC), but should be written hyphenated by octets (e.g. 12-34-56-78-9A-BC). These addresses are physical station addresses, not multicast nor broadcast, so the second hex digit (reading from the left) will be even, not odd. At present, it is not clear how the IEEE assigns Ethernet block addresses. Whether in blocks of 2**24 or 2**25, and whether multicasts are assigned with that block or separately. A portion of the vendor block address is reportedly assigned serially, with the other portion intentionally assigned randomly. If there is a global algorithm for which addresses are designated to be physical (in a chipset) versus logical (assigned in software), or globally-assigned versus locally-assigned addresses, some of the known addresses do not follow the scheme (e.g AA0003; 02xxxx). 00000C Cisco 000020 DIAB (Data Intdustrier AB) 000022 Visual Technology 00002A TRW 00005A S & Koch 000065 Network General 000089 Cayman Systems Gatorbox 000093 Proteon 00009F Ameristar Technology 0000A9 Network Systems 0000AA Xerox Xerox machines 0000B3 CIMLinc 0000C0 Western Digital 0000DD Gould 0000E2 Acer Counterpoint 000102 BBN BBN internal usage (not registered) 001700 Kabel 00AA00 Intel 00DD00 Ungermann-Bass 00DD01 Ungermann-Bass 020701 MICOM/Interlan UNIBUS or QBUS machines, Apollo 020406 BBN BBN internal usage (not registered) 02608C 3Com IBM PC; Imagen; Valid 02CF1F CMC Masscomp, Silicon Graphics 080002 Bridge 080003 ACC (Advanced Computer Communications) 080005 Symbolics Symbolics LISP machines 080008 BBN 080009 Hewlett-Packard 08000A Nestar Systems 08000B Unisys 080010 AT&T 080014 Excelan BBN Butterfly, Masscomp, Silicon Graphics 080017 NSC 08001A Data General 08001B Data General 08001E Apollo 080020 Sun Sun machines 080022 NBI 080025 CDC 080028 TI Explorer 08002B DIGITAL 080036 Intergraph CAE stations 080039 Spider Systems 080045 Xylogics??? 080047 Sequent 080049 Univation 08004C Encore 08004E BICC 08005A IBM 080067 Comdesign 080068 Ridge 080069 Silicon Graphics 08006E Excelan 080075 DDE (Danish Data Elektronik A/S) 08007C Vitalink TransLAN III 080080 XIOS 080086 Imagen/QMS 080087 ???? 080089 Kinetics AppleTalk-Ethernet interface 08008B Pyramid 08008D XyVision XyVision machines AA0000 DIGITAL obsolete~ AA0001 DIGITAL obsolete~ AA0002 DIGITAL obsolete~ AA0003 DIGITAL Global physical address for some older DEC interfaces AA0004 DIGITAL Local logical address for systems running DECNET Some Known Ethernet Multicast Addresses 3/16/89 Ethernet Type Address Field Usage Multicast Addresses: 09-00-02-04-00-01? 8080?
