Have you considered that, by design, the same address is used
not only when the lease is renewed before it expires, but also
on any later occasion when an address is requested for what
appears to be the same machine (same uid, if any; otherwise
same hardware address) UNLESS it was necessary to give away
the address in order to satisfy a request from an unknown
machine? This should only happen when all addresses in the
pool are marked 'used'; in this case, offering a 'free' address
is preferred to refusing to offer any address.
Unless your pool is too small to accommodate the number of
machines you're planning to serve, normal default lease
management may be sufficient to meet your requirements.
If you feel that this approach still involves more risk
than you're prepared to bear, you may find it useful to
search the mail archives for "reserved lease" or the like.
I hope this helps (and that I'm not mistaken).
