- 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.

- Some Known Ethernet Vendor Addresses 3/16/89
-
- Ethernet hardware addresses are 48 bits, expressed as 12 hexadecimal digits
- (0-9, plus A-F, capitalized). 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).
