MAC Address Lookup (Vendor Finder)
Runs 100% in your browser — your files never leave your device.
A MAC address on your network tells you who built the device before you ever find it. Paste an address in any common format (20:37:06:12:34:56, dashes, or dots) and get the registered vendor with its address details from the IEEE OUI database. The registry loads once into your browser; the lookup itself never leaves your device.
How it works

Paste a MAC address
Colon, dash, dot, or no separators — all formats parse.
- 2
Look up the vendor
The first three bytes are matched against the IEEE OUI registry.
- 3
