RPZ Still Doing Recursive Lookups

I am seeing that even with a zone included in an RPZ, the BIND server is still going out to the Internet to resolve the name. I was hoping the RPZ entry would stop processing short of that. I have some.bad.domain.tld returning NODATA. The client is getting the response I expect. The SOA is for

Not exactly sure what you are doning since we don’t see what records you’re trying to add, but it sounds like you are “attempting to add a CNAME alongside a non-CNAME” which doesn’t make sense and will fail. A CNAME means "use the records for this other name whenever this name is queried.” It

In order to make the determination whether to apply an rpz-nsip rule, the DNS server must have the NS records and their corresponding A records. In a recursive resolver, it would have had to lookup said NS and A records to find the answer to the query, so they are cached and available. In a

No idea if this is the best way. It is a way. Do you control any other zone? Let’s say you own “example.com.” You can tell ISC DHCP to build the reverse zone at an arbitrary base name instead of in-addr.arpa. Configure DHCP to put the reverse records at say, “rev.example.com.” So you’ll get
