MAC Address Generator Guide

About this tool

Generate random MAC addresses, optionally holding a prefix so the result stays inside a vendor range you specify.

Questions

Can I use a generated MAC on a real network?
Only after checking your network’s rules and that the result does not clash with another device. The tool does not check the network or set the locally administered bit for you. Choosing an appropriate first byte helps avoid impersonating a vendor, but it is not a collision guarantee.
