Re: [PLUG] dhcp server is too ambitious

Try something similar to this, notice there is no range line:

ddns-update-style none;
shared-network starforce {
subnet 10.10.10.0 netmask 255.255.255.0 {
        option routers 10.10.10.1;
        option subnet-mask 255.255.255.0;

        option domain-name "starforce.com";
        option domain-name-servers 10.10.10.1;

        host blacktiger {
                hardware ethernet 00:50:DA:79:4A:91;
                fixed-address 10.10.10.2;
        }

        default-lease-time 21600;
        max-lease-time 43200;

}
}
