As Glenn says, it is **REQUIRED** behaviour to give each client the
same lease as it had last time - and the ISC server goes to some
lengths to do this. It is possible to make clients change address
periodically from the server end, but it requires a fair amount of
work and all the methods I know of are horrible kludges.
If you have control of the clients, then it's possible to do it by
getting the client to ask for some other random address.
The obvious question is ... what are you trying to achieve ?
