Every network device's MAC address starts with a 3-byte OUI (Organizationally Unique Identifier) that the IEEE assigns to its manufacturer. Feed this tool a MAC address and it looks that prefix up in the official registry, then tells you which company built the hardware.

Looking up a MAC address like this returns the registered manufacturer:

3C:5A:B4:12:34:56 Google, Inc.

Can a MAC address reveal my exact device model?

No. It identifies the manufacturer through the OUI, not the specific model, and it tells you nothing personal about the device owner.

Why does the lookup fail for some addresses?

Locally-administered or randomized MAC addresses, common on modern phones for privacy reasons, don't map to a registered manufacturer. Those won't return a vendor.

Where does the vendor data come from?

The IEEE's public OUI registry, which manufacturers register with whenever they're assigned a block of MAC addresses.

Does this tool store the addresses I look up?

The lookup exists to identify a device vendor for troubleshooting or inventory purposes, not to track or log individual users.
