About the MAC Address Generator

What people use it for
- Creating test data for a network application.
- Setting a locally administered address on a virtual interface.
- Populating a lab environment.
Frequently asked questions
Do I need an account to use the MAC Address Generator?
There is no cost and no cap. The MAC Address Generator is not a demo of a paid product, so nothing is held back or watermarked.
Can you see what I put into this tool?
No. The MAC Address Generator runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
When would I actually need the MAC Address Generator?
Typical uses: creating test data for a network application. Setting a locally administered address on a virtual interface. Populating a lab environment. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Will this work on a tablet?
Yes. The page is responsive and the tool works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
