MAC Address Lookup
FreeLook up the manufacturer and vendor of any MAC address
About MAC Address Lookup
Every network device carries a MAC address, and the first half of it quietly tells you which company built the hardware. When you spot an unfamiliar gadget on your router's connected-devices list, that string of hex is often your only clue. This lookup tool turns it into a real manufacturer name so you can tell a printer from a phone from something that shouldn't be there.
Paste any MAC address and the tool reads its OUI (the vendor portion) against the public registry to return the maker and vendor details. It runs in your browser, costs nothing, and gives you an answer in a second. No account, no install, and you can check as many addresses as you like.

FAQ
What part of the MAC address is actually checked?
Only the first three bytes (the OUI) identify the manufacturer. The remaining bytes are a unique device serial that no public database can resolve to a person.
Can this reveal who owns the device?
No. It only returns the company that made the network chip. It cannot tell you the owner, location, or any personal details.
Do randomized MAC addresses work here?
Phones often use private random MACs for privacy. Those usually return no real vendor because the OUI is locally assigned rather than registered.
Can I use MAC Address Lookup on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
