What does it do?

MACLookup is a tool that makes it simple to search for MAC address prefixes and determine the manufacturer of the associated device's chipset.
It utilizes various databases, which are widely recognized and reputable sources for this information. The user simply inputs the MAC address prefix and the tool returns the manufacturer's information.


We continuously update our database by incorporating new information from the IEEE directory and Wireshark manufacturer database. The database contains over 47K mac address prefixes.


You can be confident that each search will yield the most accurate information regarding the manufacturer, vendor or organization, without the need to keep updating a database.


Our comprehensive dataset comprises MAC prefixes that are updated daily and can be obtained for no cost. The database can be downloaded in various formats from the link provided here.


The publicly available API can be accessed free of charge and it is optimized to handle a large number of requests with minimal delay.
