subnet 10.0.0.0 netmask 255.0.0.0 {

        option routers          10.0.0.1;
        option subnet-mask      255.0.0.0;
        option domain-name      "csie.ntu.edu.tw";
        option domain-name-servers 8.8.8.8;

        default-lease-time 864000;
        max-lease-time     1728000;

        #Static binding
        host delta_00_16_E6_4F_7E_D3 {
        hardware ethernet 00:16:E6:4F:7E:D3;
        fixed-address 10.7.0.80;
        }

        #PXE options
        next-server 10.0.0.1;
        filename "pxelinux.0";

        range dynamic-bootp 10.0.1.0 10.0.1.254;
}

Don't forget you must have an IP in the subnet.
Start dhcp service and enjoy it.
