Consider the following. I have two domains and using Windows 2016 DNS servers:
I wish to be authoritative for test.dom but forward sub.test.dom to another DNS server. I cannot do so as if I am authoritative for test.dom I cannot create a conditional forwarder for <anything>.test.dom. Now, if I do the following I can create a conditional forwarder for sub.test.dom:
Create a DNS Delegation to another DNS server (can be a fake/dummy one) for sub.test.dom
Create a conditional l forwarder for sub.test.dom
I don't understand though:
Q1: How this is possible/makes sense?
Q2: Which one wins/is used when I query for sub.test.dom
Q3: Which one wins/is used when I query for host.sub.test.dom
