A new Request for Comments is now available in online RFC libraries. RFC 7858 Title: Specification for DNS over Transport Layer Security (TLS) Author: Z. Hu, L. Zhu, J. Heidemann, A. Mankin, D. Wessels, P. Hoffman Status: Standards Track Stream: IETF Date: May 2016 Mailbox: zihu@outlook.com, liangzhu@usc.edu, johnh@isi.edu, allison.mankin@gmail.com, dwessels@verisign.com, paul.hoffman@icann.org Pages: 19 Characters: 42138 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-dprive-dns-over-tls-09.txt URL: https://www.rfc-editor.org/info/rfc7858 DOI: http://dx.doi.org/10.17487/RFC7858 This document describes the use of Transport Layer Security (TLS) to provide privacy for DNS. Encryption provided by TLS eliminates opportunities for eavesdropping and on-path tampering with DNS queries in the network, such as discussed in RFC 7626. In addition, this document specifies two usage profiles for DNS over TLS and provides advice on performance considerations to minimize overhead from using TCP and TLS with DNS. This document focuses on securing stub-to-recursive traffic, as per the charter of the DPRIVE Working Group. It does not prevent future applications of the protocol to recursive-to-authoritative traffic. This document is a product of the DNS PRIVate Exchange Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
