I’m studying for a certification at the moment so I know a medium amount about the structure of subletting. The one thing my courses don’t explain very well is the actual function/process of how this works.
Specifically one thing I learned really upended my understanding. The example was if you have a host with the address 10.1.16.42/24 and a host with the address 10.1.16.200/16 would they need a router to communicate?
From my understanding they would, the first host is on the network 10.1.16 and the host section is 42. The second one is on 10.1 and the host section is 16.200. Since their network sections are different why do they not need a router to communicate if their network id’s aren’t the same?

The problem with your example is that you’ve got two hosts in the same network, going by the smaller of the two, but with different network masks. This would be a configuration error in practice, and would definitely cause problems that having a router in between them wouldn’t be able to help with.
If both hosts had /24 as their network masks, then they would be in the same network, because the bitwise mask operation would return the same network number for both.
