Every network interface has a MAC address. It's bits long, written as pairs of hex digits. Example: 00:1A:2B:3C:4D:5E. The first bytes form the OUI (Organizationally Unique Identifier), assigned to manufacturers. The last bytes are chosen by the manufacturer. MAC addresses identify devices on the local network. I'll show you special MAC types next.
