What is a MAC address?
A MAC (Media Access Control) address is a 48-bit hardware identifier assigned to a network interface, written as six pairs of hexadecimal digits. It identifies devices on a local network. This tool generates random MAC addresses for testing and reformats existing ones between common notations.
Notations
- Colon —
00:11:22:AA:BB:CC(most common, Linux/macOS). - Hyphen —
00-11-22-AA-BB-CC(Windows). - Dot —
0011.22AA.BBCC(Cisco).
Note: Generated addresses are random and intended for testing. The “locally administered” bit is set so they don't collide with real vendor-assigned addresses.
