37.5.11.5.5 Ethernet Address
The Ethernet Individual Address (IA) is a 6 byte field that must be unique for each
adapter card, and thus unique for each MAC. The first three bytes define a group of
Individual Addresses which are allocated to a specific vendor - for example, [00 AA 00]
or [E9 07 00] was allocated for certain Intel products. The remaining three-bytes are
allocated in manufacturing to form a unique value for each EEPROM image. These
values change regularly as new products are introduced and/or allocated during in
production. The value from this EEPROM field is loaded into the Receive Address
Register 0 (RAL0/RAH0).
For the purpose of this specification, the IA byte numbering convention is indicated
below:
