What subnet mask do you use?
If you use the class B subnet mask (255.255.0.0), it should work. If you
use 255.255.255.0, you must be having a router between the 172.16.1.0 net
and the 172.16.4.0 net. This router can most likely be configured to
forward DHCP requests to the DHCP server.
Remember the difference between subnets and subnet address ranges. You have
a subnet, and within this subnet you have an address range. For example,
you can reserve addresses 172.16.1.0-172.16.1.10 for routers, servers etc.,
and let the DCHP server hand out addresses 172.16.1.11-172.16.1.254 to
For redundance, you have two choices:
1. Have one server running, and another server configured, ready for a
2. Configure and run two DHCP servers. This is OK, as long as they don't
hand out from the same address range.
