The dhcp server attempts to ping an address that it thinks should
be available before offering it to a client, so most of the time
it will work to have static IPs or addresses handed out by a
different server with the same range, but there is always a
change of a race where the same address is given out by both
at the same time.

You can make the netmask 'wider' if you need more addresses.  The
common 255.255.255.0 gives you 256 addresses. 255.255.254.0 would
give you 512, 255.255.252 would be 1024, etc.  As long as you
stay in the reserved private space you only have to worry about
conflicts within your own organization (until someone decides
to make private connections with another organization...).
