Does someone have a list of the IEEE assigned 3 byte hardware ethernet address prefixes and the vendors that they have been assigned to? I seem to remember someone posting a list like this a while ago. 08:00:20:XX:XX:XX Sun Microsystems, Inc.

Since many people are talking/requesting this information, I will
post the information I have. I would like to thank Michael Patton
from Laboratory for Computer Science MIT for his updated versions.
These versions, as a previous posting mentioned, are available
via anonymous ftp from pprg.unm.edu (129.24.13.10) in /pub/rfc/*
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 "Ethernet Type" or "IEEE802.3 Length"
field. The "Ethernet Type" values are managed by XEROX. Some
assignments are public (see + below), others private. Current
information includes: Xerox Public Ethernet Packet Type
documentation(Xerox Courier Vol. 3 Issue 4 October 1988); IEEE802.3
Std; NIC RFC1010; contributions from network managers and vendors.

+ These protocols are mentioned by Xerox in their October 1988 issue of
COURIER (page 8-9) as the publicly assigned numbers. Only vendors are
listed by Xerox, not what protocols. For more information about type field
assignments, contact: Pam DuPuy, Xerox Systems Instuture, (408)737-4652.
@ According to the October 1988 issue of COURIER (page 8), "if it is less
than 600H, the packet is assumed to be an 802.3 packet; if it is greater
than 600H, the packet is flagged as an Ethernet packet."
Some Known Ethernet Vendor Addresses 12/5/88
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.
