Sorry, but I understand this less than I understood your first
message :) -- there is no such concept of an "empty IP adresses" and the
range of IP addresses available via DHCP does not depend on the
allocation process (though the range of adresses actually used will
depend on the method... and on the bumber and timings of the client
requests, as the manpage hints).
To clarify your problem and your need, the best would be to give a step
by step example up to the point where the problematic situation occurs,
and compare it with the expected situation, e.g.
"1) The server is started with a range of available IPs from
192.168.0.1 to 192.168.0.30.
2) client A requests an IP and gets 192.168.0.1.
3) ...
...
N) 'X' then happens."
I would prefer to see 'Y' happen, rather than 'X', at step N."
This mode of problem description will be far less susceptible to
ambiguity.
Amicalement,
