DHCP Server Range=1 Question

I have a question about setting up the Beagleboard as a dhcp server,
specifically on setting up /etc/dhcp/dhcp.conf. I want to set the
range of ip addresses to hand out to equal 1, but I want the server to
be able to hand this ip address to multiple computers.

i.e. Code:

subnet 10.77.65.0 netmask 255.255.255.0 {
   range 10.77.65.2 10.77.65.2;
   default-lease-time 600;
   max-lease-time 7200;

The problem is that when the server hands out a lease to the first
computer, when I unplug and reconnect to a second computer the server
will not hand out the same ip address and the second connection will
not be made. I need a way for this same ip address to be handed out to
both computers without having to wait for the previous dhcp lease to
end. I have tried setting the lease time to very short (i.e. 10
seconds) which seems to work, but I don't know enough about dhcp to
know the disadvantages of this solution. The only problem I can forsee
at the moment is that the /var/lib/dhcp/dhcp.leases file will get
huge. Can someone help me with this solution? Will my solution work?
Is there a better solution?

Thanks a lot!
