Hi Carsten,

If the person you gave the MAC address to is connected to the same network as that device, then yes it is possible to find it and therefore connect to it. However, outside of the network the device is connected to, it more or less means nothing.

As for your second question, yes it is possible to 'fake' a MAC address, by using certain software to emulate it. However, it is not possible to change a MAC address, as they are essentially hard coded into the device upon manufacturing.
