Pyoui
OUI stands for Organizationally Unique Identifier. In every electronic device which has a MAC address, the first (most weighted) 24 bits are the OUI, and they identify the vendor of that device.
Usually, when you are sniffing network traffic you can be interested in which network cards are louding out there or even if the MAC address is faked. This console python program is intended to help you such things.
A little example:
$ pyoui 00:1d:60:ae:e3:42 00:80:5A 00:1A:16:7B:27:D9
