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.

Vendors

We update the MAC address lookup database as soon as we have new information from the IEEE database and Wireshark manufacturer database. There are more than 77K MAC address prefixes in the database.
The database was last updated on 3 November 2026

Data

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