Unbound has that as a possibility in the recursive DNS resolver.

Super simple to set up too:

        # Enforce privacy of these addresses. Strips them away from answers.
        # It may cause DNSSEC validation to additionally mark it as bogus.
        # Protects against 'DNS Rebinding' (uses browser as network proxy).
        # Only 'private-domain' and 'local-data' names are allowed to have
        # these private addresses. No default.
