MAC (OUI) Database

MAC (OUI) Database #

Description #

This application contains a database of Organizational Unique Identifiers (OUIs).

OUIs are the first 24 bits of a MAC address (Bluetooth or Ethernet) and the list is managed by the IEEE.

With this application you can see which company owns a MAC (e.g. 00:09:2D for HTC), or vice versa see which MAC addresses a company has registered.

Before you can use this application, you will need to download a copy of the OUI database. To do that press Menu->Update DB. I refresh and upload this database weekly.

In the next few days I will release a windows application which can be used to create that database so you can update it manually.

For more information about OUIs see here: http://standards.ieee.org/develop/regauth/oui/public.html

Notes #

  • Before you use this application, you need to download a copy of the OUI Database. To do that, Press Menu->Update DB. Keep in mind it is about 0.5MB.
  • To perform a wildcard search, use the percentage sign (%). So typing “HT%” will search for all items which start with “HT”.
  • The search is case insensitive.
  • In the MAC field enter only the first 6 characters of the MAC you are looking for. You can still enter less if you use a wildcard. Any delimiter symbols (such as : or -) will be automatically removed.
