Title : Wrapping Last-Hop DNS for Traffic Protection

DNS queries from one resolver to an upstream resolver are often run
over connections with no protection of any kind. The stub resolvers
that initiate queries for an application are ofte called "last-hop",
and their queries go to trusted recursive resolvers. The connection
between last-hop resolvers and their upstream resolver is currently
susceptible to both malicious and unintentional alteration that
prevents the querying resolver from being sure that the results it
receives are valid. Some middleboxes can prevent a stub resolver,
even one that does DNSSEC validation, from getting enough information
to validate a response. Further, a non-validating stub resolver is
susceptible to active attacks in which the results are purposely
altered.
The protocol described in this document provides a method to avoid
these problems and thus make resolution significantly more secure.
This protocol can be used between any two DNS resolvers, but the
focus of this document is on last-hop resolvers.
