Forward Lookup Zone / Conditional Forwarder Preference Order

Question

_{Tuesday, March 12, 2019 4:24 PM}

If I add a Conditional Forwarder for somedomain.net and a Forward Lookup Zone for subdomain.somedomain.net when running DNS queries which will take precedence? Is there any documentation on this?

Hi,

A DNS server configured to use a forwarder behaves as follows:

1. When the DNS server receives a query, it attempts to resolve this query using the primary and secondary zones that it hosts and its cache.
2. If the query cannot be resolved using this local data, then it will forward the query to the DNS server designated as a forwarder.
3. The DNS server will wait briefly for an answer from the forwarder before attempting to contact the DNS servers specified in its root hints.

So, the forward lookup zone has a higher priority.

Best regards,

Travis
