WhatMac is a community project that is intended to create a searchable database utilizing the first four bytes of a mac address.

The goal is to be able to identify individual devices for either Wireless, Bluetooth, or Wimax.

Keep a list of your own wireless devices and its mac addresses

Contact another user by its device type to comment support and possible problems with the devices!

This is not a database of OUI manufacture data. It's a database associating mac address with device types

For example, given the following four bytes 58:67:1A:00, you can identify this as wireless enabled Barnes and Noble Nook color.
