Yes. All clients can reach the dhcp server via tcp/udp/icmp.

subnet 192.168.29.0 netmask 255.255.255.0 {
         option domain-name "ctl.mr.lfmg.de";
         option broadcast-address 192.168.29.255;
         option routers 192.168.29.5;

         pool {
                 range 192.168.29.100;
         }
}

The 29er network is only for servers. There are no dhcp clients. But I had to 
define at least one IP in a range statement, otherwise dhcpd complained.

Hosts with static or static-via-dhcp addresses stay allways in the zonefiles. 
Dhcpd don't touch them. But they were not added automatically. This ones I had 
to add by hand.
