No history yet
This tool creates a single random MAC address for network testing, sample data, documentation, and development. A MAC address is normally displayed as 12 hexadecimal characters. The generator lets you change how those characters are grouped without changing the underlying address value.
This page generates one address at a time and keeps a short local history. If you need many addresses in one operation or want TXT and CSV downloads, use the Batch Random MAC Address Generator instead.
The output is intended for testing and example data. A randomly generated address is not guaranteed to be globally unique or assigned to a real hardware vendor. Do not use it as proof of device identity or ownership.
