A new Request for Comments is now available in online RFC libraries. RFC 8145 Title: Signaling Trust Anchor Knowledge in DNS Security Extensions (DNSSEC) Author: D. Wessels, W. Kumari, P. Hoffman Status: Standards Track Stream: IETF Date: April 2017 Mailbox: dwessels@verisign.com, warren@kumari.net, paul.hoffman@icann.org Pages: 13 Characters: 27110 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-dnsop-edns-key-tag-05.txt URL: https://www.rfc-editor.org/info/rfc8145 DOI: 10.17487/RFC8145 The DNS Security Extensions (DNSSEC) were developed to provide origin authentication and integrity protection for DNS data by using digital signatures. These digital signatures can be verified by building a chain of trust starting from a trust anchor and proceeding down to a particular node in the DNS. This document specifies two different ways for validating resolvers to signal to a server which keys are referenced in their chain of trust. The data from such signaling allow zone administrators to monitor the progress of rollovers in a DNSSEC-signed zone. 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.
