Appendix D. Ethernet Address Assignments
Ethernet Address Assignments
Ethernet addresses are often written in several different forms, and displayed as 6 hexadecimal numbers:
080023AF54F708-00-23-AF-54-F708 00 23 AF 54 F708.00.23.AF.54.F7

Vendor Addresses
The first 3 hexadecimal digits are assigned (by the IEEE) to vendors. This is a partial list of vendor-assigned (Ethernet) MAC addresses.

Ethernet Multicast Addresses
An Ethernet multicast address consists of the multicast bit, the 23-bit vendor component, and the 24-bit group identifier (assigned by the vendor). For example, DEC is assigned the vendor component 08-00-2B, so multicast addresses assigned by DEC have the first 24-bits 09-00-2B (since the multicast bit is the low-order bit of the first byte, which is "the first bit on the wire").
