I don't think this is working nslookup facebook.com unboundIP Server: UnKnown Address: unbound IP Non-authoritative answer: Name: facebook.com Addresses: 2a03:2880:f101:83:face:b00c:0:25de 188.8.131.52 I run an unbound-control reload before to read the config file again and flush the cache. What if I create a wildcard forward zone and send it to something like i.am.not.resolving.this.net?

I don't want them answered at all. The endpoints that will be configured with that DNS server must only be able to resolve the domains that I will specifically configure with a forward zone. Everything else must be denied, sorry if I wasn't clear enough in my initial query. > Guess I misread that. Then don't use a wildcard forward and drop the validator module from the configuration): module-config: iterator Then unbound can only answer the configured forwards, stub-zones, and local data. Is that what you want?
