Little program to lookup the vendor string for MAC addresses.
The first 3 octetts of a MAC address denote the manufacturer of the network card. I use this at work, when analyzing unknown or unwanted traffic, to know who the culprit may be.
python3 oui.py MAC [--force] [--file /var/tmp/oui.txt] --force - Forces the download of the file, ignoring the one week caching --file - Overrides the storage location and also uses an existing file.
