> Rather than distinguishing between private/local networks vs. Internet, it could distinguish home/enterprise networks or whether infrastructure is available to aid the discovery or not. For example, some enterprise networks may have servers (such as a Windows Active Directory Domain Service) to help assist in the discovery of DNS resolvers. This would not be possible in many home networks on the other hand. 

Practically speaking, it might help to think of this in terms of scenarios rather than types of networks.   It’s true e.g. that a corporate network may have WADDS, but it may also not.  What matters is whether it has it, not whether it is a corporate network.   It might help with clarity if we think about it this way, although I agree with your basic point.

And then what is it about WADDS that makes it able to help the client to find a secure resolver, as compared to unauthenticated DHCP?   Is it a property that is unique to WADDS, or is WADDS implementing an example of some property that other services might also be able to implement?
