Identify the manufacturer (vendor) of any device using its MAC address or OUI.
Our MAC Address Lookup Tool (also known as an OUI Lookup) allows you to identify the manufacturer of a network device using its physical MAC address. Every network interface card (NIC) has a unique Media Access Control (MAC) address assigned by the manufacturer. The first 6 characters of this address (the Organizationally Unique Identifier or OUI) are registered to a specific vendor (like Apple, Cisco, Intel, or Dell). This tool queries the IEEE OUI database to instantly reveal who manufactured the device.
Enter a full MAC address (e.g., 00:1A:2B:3C:4D:5E) or just the OUIWe extract the first 6 hexadecimal digits (the OUI prefix)Our system searches the official IEEE registration databaseThe registered vendor name (manufacturer) is retrieved and displayedThis works for Wi-Fi cards, Ethernet ports, Bluetooth adapters, and more
