MAC Vendor Lookup

Identify the hardware manufacturer behind a MAC address from its OUI prefix, and read the address bits that tell you whether it is globally unique or locally administered. Accepts any common MAC format.

The bit analysis runs entirely in your browser. The vendor name is fetched live from maclookup.app's public OUI service; nothing is sent to UniCybers servers and no lookups are stored. Locally administered or randomised MACs (common on modern phones) have no registered vendor by design.
