   Many have a hardware reset that will reset to a factory address.   
   (Like hold the reset button for 15 seconds, or hold it while   
   powering on.)

   It isn't always easy.  The device might not send at all unless data   
   is coming in.  You can try a sniffer, though.  Sometimes there is   
   a serial port, or other non-TCP way to get the address.

   A sniffer will do, in addition to the problem that an ethernet   
   switch might not forward it to you.
