OUI Lookup is a website founded in early 2020 that aims at providing the latest information about MAC addresses and MAC vendors.

We are managing a huge database provided by the IEEE institution (Institute of Electrical and Electronics Engineers) that ensures that you are provided with correct and double-checked information.

OUI Lookup is divided into two parts :

  • Blog section : where you can find interesting articles about MAC addresses and devices (phones, computers or operating systems)
  • OUI pages : they provide you with in-depth information about MAC addresses and how they are related to specific vendors.
