Multiple devices shown with (invalid?) MAC addresses starting with 52:D4:F7

My Devices list in Fing Desktop includes six devices whose MAC addresses begin with 52:D4:F7, but when I search for an OUI for 52:D4:F7 either in Fing Desktop or using any of the online MAC lookup tools, nothing is found. Apparently, 52:D4:F7 is invalid, but if so, how can I have six different devices with six different MAC addresses all beginning with 52:D4:F7?

    I forgot to mention, but the six devices I mentioned appear to be from six different manufacturers. The only way this would make sense is if the OUI is a chip manufacturer and all six devices use chips from the same manufacturer. Even if this is accurate, it doesn't help determine who the manufacturer is. I'm confused.
