OUI Lookup and Database

Alberto Pedron

About this app

With OUI Lookup you can figure out who manufactured a device simply by inserting its MAC address in the search bar.
You can also search for a manufacturer and see its assigned OUIs.

Features:

• Trusted source - The database is sourced from the IEEE to be as correct and updated as possible.
• Works Offline - OUI Lookup works completely offline, an internet connection is only needed to update the database.
• Bulk lookup - You can paste a comma/semicolon/whitespace/new line separated list of MAC Addresses to perform a multiple lookup.
• Auto-paste from the clipboard when there is one or more MAC addresses
• Dark theme is supported

Ratings and reviews

The database has not been updated for7 months. I like the way that manufactures are displayed as the MAC OUI is entered.

Simple and serves the purpose.

very useful tool if you use it properly.
