Wonder if it would be possible to (ab)use DHCP for this. If every
device registers itself with a central DHCP server, you could query
that to find out what's around, and configuring of IP addresses would
then be out of your hands.

Or can you simply use a stupid netmask like /1 that picks up all the
IP ranges? That way, the source-IP check wouldn't fail.
