Short answer : If you have both clients with real server and clients
on domU, the easiest way is to treat domU like a real server.

That means you should assign IPs in small blocks. For example, if you
have a big 10.11.25.0/24 address space, you give them out in small
blocks : 10.11.25.0/29, 10.11.25.8/29, and so on. If they need
additional address, you can route it via their existing address. Each
domU is connected via its own bridge to dom0.
