If I read this right, you have a relay box of some sort, and you want
to somehow second guess the IP address the client is going to get -
in advance of the server allocating it ?
Put simply, without complete visibility of the internal state of the
server then it is not determinable in the general case. You would
have to have a complete knowledge of the state of all leases/unused
addresses to be able to take a good guess - and then it's not
guaranteed.
Perhaps if you could describe what you are trying to achieve then
someone might be able to suggest something.
