The MAC Address Lookup is used to find the real manufacturer or vendor OUI (Organizationally Unique Identifier) of your network card based on your network card MAC address. It also allows you to find MAC address records according to the company name.

MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications on the physical network segment. It usually encodes the manufacturer’s registered identification number.

If you want to find the manufacturer a certain MAC address belongs to, enter your full MAC address or first 6 hexadecimal digits. This tool support most of the common formats such as 00-10-fa-c2-bf-d5, 00:10:fa:c2:bf:d5, 0010.fac2.bfd5, 00 10 fa c2 bf d5, or 0010fac2bfd5.

If you want to find a list of MAC address prefixes based on the manufacturer, simply enter the full or part of the company name, for example, apple or Apple Computer, Inc. The string entered into the tool is case-insensitive.

The data source of the MAC address database used in this tool is from IEEE[1].
