MAC Address Vendor Lookup

Runs in your browser — nothing is uploaded

About this tool

Decodes what a MAC address's own bits tell you (universal vs. locally-administered, unicast vs. multicast — always 100% accurate, since it's just IEEE 802 bit rules) plus a best-effort vendor name from a small hand-picked list of well-known prefixes.

The vendor list below covers a few dozen well-known prefixes only — it is not the full IEEE OUI registry (35,000+ entries) and isn't authoritative. For anything that matters, check the official IEEE OUI registry directly.
