What is a MAC address?
A MAC address (Media Access Control) is a unique 48-bit (6 bytes) identifier assigned to each network interface. It is typically represented as 12 hexadecimal digits.
The first 3 bytes (24 bits) form the OUI (Organizationally Unique Identifier) identifying the manufacturer. The last 3 bytes are unique per device.
Tip
Combine it with the OUI Lookup to verify which manufacturer corresponds to each prefix.

- Generate MACs for virtualization and container environments
- Configure MAC whitelists in enterprise WiFi networks
