This whitepaper details a way of making DNS cache poisoning / response spoofing attacks more reliable. A caching server will store any NS delegation RRs if it receives a delegation which is "closer" to the answer than the nameservers it already knows. By spoofing replies that contain a delegation for a single node, the nameserver will eventually cache the delegation when we hit the right transfer id.
