Network tool FAQ
What is an OUI prefix?
An OUI is the first six hexadecimal characters of a MAC address assigned to an organization.
Can this identify the exact device?
No. It identifies the registered prefix owner, not the exact device model or current owner.
Why is a vendor missing?
The prefix may be private, randomized, newly assigned, or absent from the public vendor list used by the tool.
Do randomized MAC addresses work?
Randomized addresses often do not map to the real device vendor and may not return a useful match.
What formats can I paste?
Colon, hyphen, dot, or plain hexadecimal formats work as long as the first six hex characters are present.
