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 MAC address lookup database as soon as we have new information from the IEEE database and Wireshark manufacturer database. There are more than 55K MAC address prefixes in the database.
