What is a MAC address?

A MAC address is a unique hardware identifier assigned to network interfaces (like WiFi cards or Ethernet ports) for communications on the physical network segment.

How does the lookup work?

The first 3 octets (24 bits) of a MAC address are known as the Organizationally Unique Identifier (OUI), which is assigned to hardware vendors by the IEEE.

Are MAC addresses routable on the internet?

No, MAC addresses are only used for local network switching. Once traffic passes through a router, the MAC address changes.
