What does it do?

MACLookup provides an easy way to search for MAC address prefixes and matches them to the chipset's manufacturer. It uses the IEEE database.


We update our database as soon as we have new information from the IEEE directory and Wireshark manufacturer database. There are more than 44K mac address prefixes in the database.


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


The pubblic Rest API is free.
API is designed for high volume requests and low latency.
