Thanks for the response, Greg.

> There are circumstances where a subset of the Internet's hosts may be reachable. For example, you may be able to reach link-local names without a broader Internet connection. Or you may be able to reach a host behind a VPN only when the VPN is active. (I don't know what Reachability actually does in these cases, but it's the sort of thing that the API was designed to handle.)

But since this test doesn't actually check the routes to these hosts,
how would it be able to provide meaningful results even in these
cases?

I figured the specific-host test pinged the host.
