Ethernet address in hex

Answer 1

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) and the last/right 6 digits which specify the interface serial number for that interface vendor.

These high-order 3 octets (6 hex digits) are also known as the

Organizationally Unique Identifier or OUI.
