When I go to my device list it automatically converts the first half of the MAC address to the NIC vendor. How do I turn this functionality off if I want to see the entire MAC address?
Click on the"Settings" button on the top left of the main Dude screen. A Server Configuration panel will open. Click on the “…” tab and then select the “Misc” setting. The panel that opens has a “Resolve MAC Address Manufacturer” checkbox. Uncheck this and bingo… you get the full MAC address displayed.
Not so simple to find but the option is there if you hunt for it. 
Happy New Year!!
Perfect, thanks for the help!
