A new Request for Comments is now available in online RFC libraries. RFC 8094 Title: DNS over Datagram Transport Layer Security (DTLS) Author: T. Reddy, D. Wing, P. Patil Status: Experimental Stream: IETF Date: February 2017 Mailbox: tireddy@cisco.com, dwing-ietf@fuggles.com, praspati@cisco.com Pages: 13 Characters: 31130 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-dprive-dnsodtls-15.txt URL: https://www.rfc-editor.org/info/rfc8094 DOI: 10.17487/RFC8094 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. This document proposes the use of Datagram Transport Layer Security (DTLS) for DNS, to protect against passive listeners and certain active attacks. As latency is critical for DNS, this proposal also discusses mechanisms to reduce DTLS round trips and reduce the DTLS handshake size. The proposed mechanism runs over port 853. This document is a product of the DNS PRIVate Exchange Working Group of the IETF. EXPERIMENTAL: This memo defines an Experimental Protocol for the Internet community.
