How can I unmask a phony mac address

I signed into my xfinity admin page to check for any unwanted connections or unknown devices. I immediately noticed a no name device under "connected devices" and marked down the machine address listed. To my surprise there is no address in the oui database. Since mac addresses technically can't be changed, I am guessing who ever no name may be, is using a mask to hide their identity. If I am correct, how do I reveal the actual mac address, and if I'm mistaken, then what's going on?

Is it address randomisation what you are seeing?

  1. At least some Ethernet adapters can transmit packets with a source address that's not the MAC address of the adapter, and can be configured to accept unicast packets to a MAC address other than the MAC address of the adapter.
  2. At least some Ethernet adapters store the MAC address in an EEPROM that can be modified.
