      1. Proposed title of this feature request

      Internal DNS authoritative for 100.64.0.0/10 PTR

      2. What is the nature and description of the request?

      Customer is experiencing an edge case where a PTR request being sent for a 100.64 (geneve) address is being forwarded to external dns. In a situation where the external dns is unreachable, this causes a failure in a tight healthcheck window. The idea behind this RFE is that if internal DNS could either reply or nx such a request instead of forwarding, this edge case would not occur.

      3. Why does the customer need this? (List the business requirements here)

      Current implementation results in unexpected failover if there is a delay in external dns nx for an internal ptr request.

      4. List any affected packages or components.
