DHCP will only hand out the "next" ('unstable') address to a host that
currently has no valid lease AND does not have a reservation set on the
DHCP server.  Reservations are based on host MAC address.

Any host that has a valid lease will renew that lease indefinitely, at
lease half-life (and if the DHCP server happens to be missing at
half-life, retry at 7/8ths ).
