Shows brief information about all the MAC addresses of the system, while it is not always easy to map an interface to specific matching MAC address.
DETERMINE DEVICE BY MAC ADDRESS WINDOWS
To find out your MAC address in Windows from the command line, open a command prompt, to do this press Win+x and select “ Windows PowerShell”. In the window that opens, the item “ Physical Address” is the MAC address of this network adapter: Select the adapter (network connection) you are interested in, right-click on it and select “ Status” in the context menu. To find out your MAC address, open Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings or you can just run the command: On Windows, you can find out your MAC address in several ways – from the GUI and from the command line. Where, instead of MAC, insert the MAC-address of interest to you (in whole or in part): oui.txt)" Įcho "For the MAC $1 the following information is found:"Įcho "MAC $1 is not found in the database." I wrote a small script that can also help you. The database is a plain text file, which you can search in various ways that are convenient for you.

How to determine the device manufacturer by MAC address in LinuxĪ database with Organizationally Unique Identifier (OUI) is usually already present on Linux systems, because various programs use it.
Įnter one or more countries to search for, separating each search string with. Įnter one or more addresses to search, separating each search string with. You can specify the complete address (for example, 01-02-03-04-05-06) or only its first 3 bytes (for example, 01-02-03).Įnter one or more company names to search for, separating each search string with. The input rules are as follows:Įnter one or more MAC addresses, separated by spaces or by pressing. You can search by MAC address, company name, company address, company country, all MAC addresses.

In Windows, there is a free program MACAddressView to determine the vendor (manufacturer) of a device by MAC address. How to determine the manufacturer of the device by MAC address in Windows The manufacturer assigns the last three octets arbitrarily and, unlike the first three, they must be unique for each network interface. It is from them, knowing the MAC address, that you can determine the manufacturer. That is, they are unique for each manufacturer of network devices, and each manufacturer, when assigning a MAC address to its network device, begins with its own three octets.

The first three octets (bits) contain the Organization Unique Identifier (OUI) or MFG (Manufacturing) code that the manufacturer receives from the IEEE.
These characters include all numbers and letters from A to F (the hexadecimal character set). That is, a MAC address consists of six pairs of characters (called octets). However, two NICs connected to two different networks can share the same MAC address.Īn example of a MAC address is 50:46:5D:6E:8C:20, notations such as 50-46-5D-6E-8C-5D6E8C20 are also common. Network nodes with multiple network interfaces, such as routers and multilayer switches, must have a unique MAC address for each NIC in the same network. MAC addresses are formed according to the principles of two numbering spaces based on Extended Unique Identifiers (EUI) managed by the Institute of Electrical and Electronics Engineers (IEEE): EUI-48, which replaces the obsolete term MAC-48, and EUI-64. The address typically includes a manufacturer's organizationally unique identifier (OUI). Many network interfaces, however, support changing their MAC address. Each address can be stored in hardware, such as the card's read-only memory, or by a firmware mechanism. MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address, or as an Ethernet hardware address, hardware address, or physical address. As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. A media access control address ( MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment.
