About MAC addresses
A MAC (Media Access Control) address is a 48-bit identifier — six bytes, usually shown as twelve hex digits — assigned to a network interface. This generator produces random, syntactically valid addresses for testing, mocking device inventories, or seeding lab environments, in colon, hyphen, or Cisco dotted notation. They're random samples, not tied to any real vendor OUI, and are generated entirely on your device.
Private & free — this tool runs entirely in your browser.
