About MAC Address Generator

The MAC Address Generator is used to generate a random MAC address, in lower or upper case for your convenience. The tool can generate four most commonly used types of MAC address formats and it is also allowed to specify your preferred MAC address prefix (specific OUI – Organizationally Unique Identifier).

Please note that the generated MAC addresses are for testing purpose only, not for production use.
