We host our DNS on Route53. For one record, we need to provide a different IP internally. It's sort of split brain, except both brains aren't hosted on 2016.
Basically, *.example.com should use the Route53 records. stupidapp.example.com should return an internal IP instead of the Route53 record (which still has to work externally).
Can I do this with Server 2016 DNS policies?
