Legacy DNS address-filter mode still accepts destination-side IP predicates with a deprecation warning, but the recent evaluate/ match_response refactor started evaluating those predicates during pre-response Match(). That broke rules whose transport selection must be deferred until MatchAddressLimit() can inspect the upstream reply. Restore the old defer behavior by reintroducing an internal IgnoreDestinationIPCIDRMatch flag on InboundContext and using it only for legacy pre-response DNS matching. Default and logical DNS rules now carry the legacy mode bit, set the ignore flag on metadata copies while performing pre-response Match(), and explicitly clear it again for match_response and MatchAddressLimit() so response-phase matching still checks the returned addresses. Add regression coverage for direct legacy destination-IP rules, rule_set-backed CIDR rules, logical wrappers, and the legacy Lookup router path, including fallback after a rejected response. This keeps legacy configs working without changing new-mode evaluate semantics. Tests: go test ./route/rule ./dns Tests: make
