This is and example of a dhcpd config file for OpenBSD. The interface fxp1 is the internal interface to my local lan. It has a static private IP (192.168.0.1) The dhcpd server is bound to it and it gives leases to my internal workstations. There are 3 workstations that get static ip's from the dhcp server. The ip's they get are based on their mac addresses. The dns server and default route is also the 192.168.0.1 mentioned above.
This example is from the /etc/dhcpd.conf file.
