Using dnsmasq, I can set new values for existing records, and add new records, event to a zone I don't own. But is it possible to mask or suppress an existing record ?
In my case I want a CNAME to be non existent and return status NXDOMAIN
But dnsmasq would'nt start. I then tried
As this is ignored, I get the real CNAME record from the real DNS servers.
