Abstract:
   DNS queries and responses are visible to network elements on the path
   between the DNS client and its server.  These queries and responses
   can contain privacy-sensitive information which is valuable to
   protect.  An active attacker can send bogus responses causing
   misdirection of the subsequent connection.

   To counter passive listening and active attacks, this document
   proposes the use of Datagram Transport Layer Security (DTLS) for DNS,
   to protect against passive listeners and certain active attacks.  As
   DNS needs to remain fast, this proposal also discusses mechanisms to
   reduce DTLS round trips and reduce DTLS handshake size.  The proposed
   mechanism runs over the default DNS port and can also run over an
   alternate port.
