Why is the zone “.” root hints and the rest of the lines commented out? Isn’t the dns cache server supposed to search recursively, meaning to start with the root hints and then go downwards until it finds the domain? If you comment out the root hints zone, how is it supposed to do that? It would need a forwarders directive.

thanks for the great info on setting the caching only dns server up with bind! I was trying to set up with both unbound on one server and bind on another and this was just what I needed. Unbound seems to not be used as much yet, maybe because it is newer than bind? In case anyone else is after unbound information I recommend checking this information which helped me a LOT:

Good luck!

Would/should this configuration be locked down tighter perhaps with an acl that would disallow access to the nameserver from unauthorized/unwanted clients that might attempt to exploit for a DOS attack on another site?

Your config:
allow-query { localhost; any; };
allow-query-cache { localhost; any; };

Suggestion:
allow-query { friends; };

acl friends {
192.168.0/24;
localhost;
localnets;
};
