> 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 port 853.
