2.1.2 IEEE Addressing
n6 bytes are used
for addressing
nA manufacturer developing MAC products buys 224 addresses
from IEEE (IEEE sets the first 24 bits and the
manufactures sets the last 24 bits) -> each MAC address is unique!
nAddresses are generally written in HEX format. Hex means each character goes from 0 to 15 (donated
by ‘F’) as opposed to decimal where a character goes from 0 to 9 or
binary from 0 to 1. Every 4 binary bits translate
into 1 hex symbol. E.g., as we have 48 bits -> we have
48/4 hex symbols and an address will be given as:
F2-05-AB-39-42-DD.
