It provides information about the manufacturer that manufactured that device, the prefix, postfix of a given MAC Address. The tool searches a given MAC Address or OUI in MAC Address Vendor Database. If you want to find a specific MAC Address manufacturer, please use our MAC Address Tracker. How do I find out where a MAC address belongs to?įor that, first get the MAC Address of a device. That allows for far more MAC Addresses compared to a 48-bit address. But for the Network Interface Controller, it goes to 60-bit. The OUI portion is the same 24-bit, like in 48-bit MAC Address. The EUI-64 is an extended unique identifier and stands for 64-bit MAC Address. Traditionally, the MAC Addresses are 48-bit in length, 24-bit for the OUI, and 24-bit for the Network Interface Controller.
Note: These generated MAC Addresses are only for testing purposes, not for production purposes. The tool processes your request and provides you with the desired result.After filling in the above requirements, click on the "Generate MAC Address" button.Select the number of random MAC Addresses you want to generate.You can choose either you need MAC Address in upper case or lower case.The tool allows you to select from the four most commonly used formats. Its maximum length must be six characters. To generate the MAC Addresses, perform the following steps. The MAC Address Generator allows you to generate the random MAC Addresses for testing purposes. How to use the MAC Address Generator to generate the random number of MAC Addresses? But, hardware devices from different manufacturers may share the same device identification address. All the devices manufactured by the same manufacturer have unique 24-bit numbers. The rightmost six digits (24 bits) are associated with device identification. What is a Network Interface Controller of the MAC Address?Ī Network Interface Controller is the part of the MAC Address that defines the device portion. The OUI of some well-known manufacturers are as follow For example, the prefixes 00-13-10, 00-25-9C, and 68-7F-74 (plus others) belong to Linksys (Cisco Systems). And it's common in large manufacturers to have more than one set of OUIs. Sometimes, manufacturers possess several prefix numbers associated with their products.
The IEEE is responsible for OUI distribution and issues it to their registered manufacturers. It's the leftmost six digits (24 bits), also called prefixes, and is associated with the hardware manufacturer.
What is an OUI MAC Address?Īn OUI (Organizationally Unique Identifier) is the part of the MAC Address that defines the hardware manufacturer. Note: Linux OS uses Colon-Hexadecimal notation, and Cisco Systems use Period-separated Hexadecimal notation.
