Frequently asked questions

What kind of MAC is generated?

It generates a MAC with the locally administered unicast bit set so it does not clash with real vendor addresses. Suitable for testing and virtual devices.

Can I change the format?

Yes. Choose colon, hyphen, or no separator, and pick uppercase or lowercase.

Is the generated value sent to a server?

No. All generation happens only inside your browser, and the value is never sent to or stored on any server.
