Mac address lookup tool is responsible for searching for mac addresses or OUI in the mac address vendor database, which contains a list of mac addresses of the registered devices to date. The addresses contain the details of the device’s original manufacturer, prefix, and postfix of the particular mac address, along with the original manufacturing country.

Once you verify your device with the original mac address, these details are important and should be connected to the OUI database’s original vendor. Media Access Control (MAC) address is an extraordinary yet important identifier assigned to the network interfaces to communicate on the section of the particular physical network.įor instance: Network Interface Card (NIC) is a unique design for storing MAC addresses. When there is a problem in your network and the users say that their IP addresses are already used, you can simply put this filter string to check the duplicated IP addresses. Which company manufactured the network card MA-L, MA-M, MA-S. And OUI is always installed with your Wireshark, so, you do not need to edit manuf or ethers configuration. It is also known as a physical or hardware address. Enter the MAC address or OUI and find which company made the device. It identifies the hardware manufacturer and is used for network communication between devices in a network segment.

Six groups of two hexadecimal digits make up the MAC Address. I have a database with many MAC addresses and I have programmed a C code that downloads the oui file from, parses it to generate a more useful file for my needs and updates the database with the manufacturer of each MAC. The network interface cards consist of MAC address which is always stored in hardware such as ROM, BIOS system, etc. The address is originally stored by the manufacturer. It is also known as Burned-In address (BIA) or ethernet address. Wireshark OUI lookup helps cyber defenders, pen testers and red teams identify and target network endpoints - and it can be accessed from any browser. Organizational Unique Identifier (OUI) is the part of the MAC address that helps identify the network adapter.Ĭisco and Dell are the most popular and well-known NIC manufacturers. The identification of OUI is the first three sets of two hexadecimal in any MAC address. OUI remains the same on NICs when manufactured by the same company. For instance, suppose a network card manufacturer by Cisco has an address “ 00-14-22-04-25-37”. This address contains the OUI of Cisco which is “ 00-14-22”.

This OUI will help you in identify the manufacturer that is Cisco. What are the Notational Conventions in MAC Address? The OUI’s are recorded and issued to the manufacturers by IEEE.
