Features include MAC address lookup, random MAC address generator, and API access to our database that you can use for whatever you want!

MAC Address Lookup - Instantly identify network device manufacturers and vendors by MAC address. Search by full or partial MAC address, or look up MAC prefixes by company name with our comprehensive OUI database.

Simply enter the MAC address or OUI, and you’ll instantly see the vendor’s name, address, and country. In addition, we provide historical data on MAC prefixes, so you can track any changes to vendor names or addresses over time.

Our MAC address lookup tool utilizes a vast database of MAC addresses and vendor names. When you enter a MAC address, our tool searches for it in the database and provides you with the associated vendor name.

An OUI {Organizationally Unique Identifier} is a 24-bit number that uniquely identifies a vendor or manufacturer. They are purchased and assigned by the IEEE. The OUI is basically the first three octets of a MAC address. For example, these are examples of OUI:

Download an exhaustive MAC Address Vendor Database for your educational, business or enterprise needs. Our database comes in the following forms: JSON, CSV, XML, Cisco vendorMacs.xml for maximum compatibility and fast integration into existing systems.

Our tool accesses this database and finds the MAC address block, which contains the inputted MAC address. Then, it pulls the relevant details from the database and outputs them to the user in a clear and straightforward format.

The Institute of Electrical and Electronics Engineers (IEEE) performs OUI assignments and maintains the OUI database. The last three octets of a MAC address are assigned by the owner of the OUI to form a globally unique device address.

You can search for any a company name, address, MAC address, etc. Donate! Pretty please?
