Can anyone recommend a strategy for finding devices with dynamic IPs?
To do somehting similar here, we use a scheme were the windows host
sends out a UDP broadcast message, and all the devices have daemon
running, listening to that broadcast, and sends back (via broadcast) a
response with the IP address and serial number embedded.
We use this to identify all running devices on the network.
This only works within the same subnet.
