What does it do?

MACLookup provides an easy way to look up MAC address prefixes and match them to the chipset's manufacturer.

MACLookup offers information on MAC address (a unique identifier assigned to a network interface), OUI (Organizationally Unique Identifier), and Vendor name. It uses the IEEE database for this purpose.

Vendors

We update MAC address lookup database as soon as we have new information from the IEEE database and Wireshark manufacturer database. There are more than 50K MAC address prefixes in the database.

 Data

For each search, you will always have the most accurate manufacturer, vendor or organization data, without having to worry about updating a database.

 API

The MAC Lookup Rest API is available for free and provides a powerful tool for retrieving detailed vendor information about any MAC address or OUI. With this API, you can seamlessly integrate MAC address and OUI lookup functionality into your applications, services, or systems. More info...
