A new Request for Comments is now available in online RFC libraries. RFC 9018 Title: Interoperable Domain Name System (DNS) Server Cookies Author: O. Sury, W. Toorop, D. Eastlake 3rd, M. Andrews Status: Standards Track Stream: IETF Date: April 2021 Mailbox: ondrej@isc.org, willem@nlnetlabs.nl, d3e3e3@gmail.com, marka@isc.org Pages: 16 Updates: RFC 7873 I-D Tag: draft-ietf-dnsop-server-cookies-05.txt URL: https://www.rfc-editor.org/info/rfc9018 DOI: 10.17487/RFC9018 DNS Cookies, as specified in RFC 7873, are a lightweight DNS transaction security mechanism that provide limited protection to DNS servers and clients against a variety of denial-of-service amplification, forgery, or cache-poisoning attacks by off-path attackers. This document updates RFC 7873 with precise directions for creating Server Cookies so that an anycast server set including diverse implementations will interoperate with standard clients, with suggestions for constructing Client Cookies in a privacy-preserving fashion, and with suggestions on how to update a Server Secret. An IANA registry listing the methods and associated pseudorandom function suitable for creating DNS Server Cookies has been created with the method described in this document as the first and, as of the time of publication, only entry. This document is a product of the Domain Name System Operations 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. Distribution of this memo is unlimited. This announcement is sent to the IETF-Announce and rfc-dist lists.
