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.ДЄn 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.
