Abstract

The Domain Name System (DNS) [RFC1035] was specified to transport DNS messages in cleartext form. Since this can expose significant amounts of information about the Internet activities of an end user, the IETF has undertaken work to provide confidentiality to DNS transactions (see the DPRIVE working group). Encrypting the DNS transport is considered one of the options to improve the situation.
