identify by MAC ID (OUI)

Every network adapter has its unique serial number (MAC number). The first six numbers show the manufacturer (OUI vendor code).
You can download the tool MACView to find the MAC of your card.


Identify network card by MAC ID (OUI) number
Enter the OUI of the MAC ID located on your adapter to obtain company information.
E.g.: If your MAC ID looks like 00-20-35-C1-FC-94 then the OUI is 002035.
