Random MAC Address Generator
Generate valid, locally-administered MAC addresses.
Valid MACs on demand
Testing network software often needs a MAC address that is valid but not tied to real hardware. This generator produces locally-administered unicast addresses — the range set aside for exactly that.
Each address is shown in colon, hyphen, and Cisco dotted notation so it drops straight into whatever tool you use. The address bits are set correctly, so the result is always a legitimate unicast MAC.
Correct and private
Generation runs in your browser, so nothing leaves your device.
