forwarding non-domain queries

[Cuttler, Brian R (HEALTH)]

Hello, looking for a sanity check.

Inside our network we are running BIND 9.18.28-0ubuntu0.22.04.1-Ubuntu on Ubuntu  22.04.5 LTS

Currently our server serves our own zones files - A/CNAME/PTR/TXT/etc records for our domain.
We have already modified the db.cache file to reference two servers provided by our corporate IT rather than using the internet root servers.
We have numerous forwarder zones for corporate zones, both forward and reverse zones.

We are looking to no longer use recursion but rely entirely on the corporate servers for anything we would normally resolve from external servers.


I think all we need to do is create a forwarders stanza set "forwarder only" , similar to(but with the correct IPS)

        forwarders {
            1.2.3.4;             # External DNS
            1.2.3.5;             # External DNS
        };
        forward only;

The desire is to continue to use our own zone files, and to continue to use the already established fowarder zones, but to replace recursion managed by our own internal servers with queries to ONLY the 2 servers we are already using as replacement root servers.

Seems so simple that I have to believe I've missed something.

Thanks in advance,
Brian
