Then you can use AUTOIP, I learned of this here, so you may find moro in 
the list's history. It selects ramdom IPs and checks if they are in in 
use...

Then you can implement something using UDP broadcast to find your board. 
Two friends have implemented something like that based on that idea: you 
bradcast a single UDP packet with an ID in it, and your board answers to 
the sender.

What I am not sure is how to get the MASK correct with AUTOIP, any ideas?
