MAC address Vendor code

Vendor codes

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.

According to some informal correspondence, when the IEEE assigns an Ethernet address block, a block of 2**25 is reserved. Both a unicast and a multicast (group address) block, in a pair. Thus multicast groups for vendor-specific uses tend to match the non-multicast vendor assignments with "010000" added. This rule seems to be true for most of the addresses in these files.

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).
