Mystery device with mysterious MAC address

So a device showed on my network with no information than the Mac address (66:52:D0:D5:86:E1) which doesn't seem to correlate to any manufacturer or even the randomized kind that Apple and other use.  Any ideas?

    This is a mystery.  I tried searching via a few Mac lookup sites and the Fing Desktop lookup tool and nada, nothing.  In cases like this, you might need to do a process if elimination, shutting down each device one at a time and ping till it becomes un-pingable so you can figure out which device it is.  Cumbersome but not sure if an easier way exists.
