MAC Address Lookup vs MACVendors.com
Both identify the hardware vendor (OUI) behind a MAC address. MACVendors.com queries the full IEEE registry online; Gera Tools' lookup maps a curated set of common OUIs to vendors entirely in your browser, and tells you honestly when an OUI isn't in its local set.
For resolving an arbitrary OUI against the full IEEE registry, MACVendors.com wins on breadth. If you want a quick vendor guess plus U/L and multicast-bit decoding without the MAC leaving your browser, Gera Tools' lookup is the private option.

FAQ
Why does Gera Tools sometimes say 'unknown vendor'?
It maps a curated set of common OUIs locally. When an OUI isn't in that set it tells you honestly rather than guessing — for full coverage, MACVendors.com queries the complete IEEE registry.
Is the MAC address sent anywhere?
No, in Gera Tools' lookup — it uses a local table in your browser. MACVendors.com queries the address server-side.
