In that case, you didn't tell dhcpd everythign it wants to knwo about your 
network setup.  DHCPd needs to know a LOT about your network setup (at the 
minimum, it needs a subnet declaration that is the exact same as your network 
card's).  Even if you only want to serve a small range of the subnet up as 
dynamic addresses, you still need to declare the entire subnet.  Then use the 
range parameter to tell it about where you actually want addresses assigned from.

Example:
subnet 192.168.17.0 netmask 255.255.255.0 {
   range 192.168.17.100 192.168.17.200;
   option routers 192.168.17.1;
   option domain-name-servers 192.168.0.1;
   option domain-name "secondary.local.lan";
}

The interface is configured as 192.168.17.1/255.255.255.0 (notice the matching 
subnet declaration).  I then use the range option to tell it that I only want 
.100-200 served as dynamic addresses.  If you have more than one IP in different 
subnets on the interface, or if more than one IP range lives on the same subnet, 
you'll want to tell dhcpd.conf abotu that too (there's a SHARED-NETWORK option 
or somethign like that for telling it about subnets on the same physical network 
that you're not actually a member of IP wise, man dhcpd.conf for more info on that).

Hope this helps.
