MAC Address Vendor Assignments - CSV
MAC Address Vendor Assignments is an allocation system for network device identifiers managed by the IEEE Registration Authority. There are three block types: MA-L (formerly OUI), MA-M, and MA-S, with unique identifiers assigned to each vendor. This enables unique identification of network devices worldwide, used in Ethernet, Wi-Fi, Bluetooth, and other communications.
