For example, let's say a network card manufactured by dell has a physical address: 00-14-22-04-25-37. OUI is always the same for NICs manufactured by the same company. The first three sets of two hexadecimal numbers in a MAC Address identify the card manufacturer, and this number is called OUI (organizationally unique identifier). There are several NIC manufacturers some well-known are Dell, Cisco, and Belkin. The physical address is stored in the NIC by its manufacturer, which is why it is also called a burned-in address (BIA) or ethernet hardware address.

The network adapters or network interface cards always come with a MAC Address fed into hardware, usually in read-only memory (ROM) or BIOS system. MAC Address usually consists of six groups of two hexadecimal digits. It identifies the hardware manufacturer and is used for network communication between devices in a network segment. It is also known as a physical or hardware address. MAC Address or media access control address is a unique ID assigned to network interface cards (NICs).

To perform the MAC Address Vendor Lookup, perform the following steps All this information is helpful if you want to verify the generated mac address with the original vendor of this device in the OUI vendor database. Moreover, it tells us what country this device was manufactured in. The MAC Vendor Lookup finds the MAC Address from this database and tells us which manufacturer originally manufactured this device and what is the prefix and postfix of a given MAC Address.

How to perform the MAC Address Vendor Lookup? The MAC Address Vendor Database consists of a list of mac addresses of all devices manufactured to date. MAC Address Lookup Tool searches your MAC Address or OUI in the MAC Address Vendor Database.
