FAQ
What is an OUI and how does it identify manufacturers?
An Organizationally Unique Identifier (OUI) is a 24-bit prefix assigned by the IEEE to hardware makers, globally binding the prefix to that company.
Why do modern smartphones sometimes report unknown vendors?
Recent iOS and Android versions enable randomized private MAC addresses by default when connecting to Wi-Fi to prevent tracking across public networks.
Does this lookup query a remote telemetry service?
No. The search queries an optimized embedded IEEE registry database locally in your browser, keeping your network MAC queries entirely confidential.
