About This Tool
A comprehensive MAC address generator tool. Besides generating random MAC addresses, it allows you to specify a vendor prefix (OUI) to simulate specific devices. You can precisely control the address type (Unicast/Multicast, Universally/Locally Administered) and flexibly adjust the output format (colon, hyphen, or no separator) and case. The tool supports batch generation of up to 100 addresses with one-click copying. All calculations are performed locally in your browser to ensure data privacy.
