MAC Address Lookup

MAC Address Lookup provides information about any MAC Address of a networking card installed into your computer or any other device. MAC Address can be located on the networking card box or through the operating system after it installs in the computer. You can view your networking card MAC Address by typing ipconfig /all in the command prompt in any windows version. The field "Physical Address" indicates your networking card MAC Address.

About MAC Address Lookup Tool

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

How to perform the MAC Address Vendor Lookup?

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. Moreover, it tells us what country this device was manufactured in. 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.

To perform the MAC Address Vendor Lookup, perform the following steps

  • Open the MAC Address Lookup
  • Enter the MAC Address or OUI.
  • The tool finds the MAC address from the MAC Address Vendor Database and displays the manufacturer originally manufactured this device.

Note: The MAC Address Lookup provides you with information on the OUIs that are registered and assigned by IEEE. However, in some cases, if you want to generate the fake MAC Address for your testing purposes, you can use the MAC Generator.

What is a MAC Address?

MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). It is also known as a physical or hardware address. It identifies the hardware manufacturer and is used for network communication between devices in a network segment. MAC Address usually consists of six groups of two hexadecimal digits.

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. 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. There are several NIC manufacturers; some well-known are Dell, Cisco, and Belkin.

What is an OUI?

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). OUI is always the same for NICs manufactured by the same company. For example, let's say a network card manufactured by dell has a physical address: 00-14-22-04-25-37. In this address, 00-14-22 is Dell's OUI, which identifies that the device is by Dell. It may be interesting to know that all the OUIs are registered and assigned to the manufacturers by IEEE.
