This is just the tip of the iceberg of what hosts
don't know about addresses. The problem is that
it is definitionally *unknowable* to the host
since only thing that has that knowledge of those
sort of topology goodies are routers, perhaps
transported by routing protocols.
This, to my mind, is the very basic reason why
SL addresses are a generally Bad Idea. Requiring
hosts to have knowledge of network topology is
a bug, not a feature.
