Your problem is using dynamic-bootp.  Take it out, make the line:
	range 10.0.0.10 10.0.0.254;

The BOOTP protocol is for old stuff like X-Terminals and some printers
(at least that's all I've ever seen.)  BOOTP has no way to release
addresses once they are assigned, so every assignment is permanent. 
Eventually you run out of addresses to assign.

After you change your dhcpd.conf file, I would shut down dhcpd and
remove all files from the /var/state/dhcpd directory (if that is where
your distro puts it.)  Then you restart the dhcpd server.  When they go
to renew their address, your clients will get new addresses.
