If the latter (which I suspect), how does hnetd communicate the list > of foos to dnsmasq? When done dynamically (i.e. by hnetd), dnsmasqs are configured to: - forward requests for non-local zones to nodes where they are based (based on HNCP state) - forward locally to the ohp local zones In my static config (which is 'official' HNCP free), I just have configuration files which mirror this idea.
