DHCP with a very small pool

[Artzi, Yoav (Yoav)]

I want to configure a DHCP server to assign a single address to a
client. My address range includes one address, and I need to connect on
client to it, however I might want to change the client machine.
However, there will never be two clients connected at the same time. So
what I want is that the server will try to give an IP, see that the
range is all distributed and then will take an existing lease and try to
see (by ping) if the client is still on the network, and if not will
void the lease and give that IP.
 
Is it possible?
 
Thanks,
 
Yoav.
