Wait... Can DNS resolvers be configured so that RFC1918 is respected?

I mean: I don't expect anything less from Microsoft than doing stuff like that and it cannot affect me for I nullroute microsoft.com from my unbound server (unboud takes wildcard when nullrouting or NXDOMAINing crap domains like microsoft.com or meta.com etc., which is sweet).

However I'd expect my trusty DNS resolver to also prevent me from anyone not on my private LANs to impersonate addresses reserved for private uses.

Does anyone know here if it's easily doable?
