A new Request for Comments is now available in online RFC libraries. RFC 7129 Title: Authenticated Denial of Existence in the DNS Author: R. Gieben, W. Mekking Status: Informational Stream: Independent Date: February 2014 Mailbox: miek@google.com, matthijs@nlnetlabs.nl Pages: 30 Characters: 62936 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-gieben-auth-denial-of-existence-dns-05.txt URL: http://www.rfc-editor.org/rfc/rfc7129.txt Authenticated denial of existence allows a resolver to validate that a certain domain name does not exist. It is also used to signal that a domain name exists but does not have the specific resource record (RR) type you were asking for. When returning a negative DNS Security Extensions (DNSSEC) response, a name server usually includes up to two NSEC records. With NSEC version 3 (NSEC3), this amount is three. This document provides additional background commentary and some context for the NSEC and NSEC3 mechanisms used by DNSSEC to provide authenticated denial-of-existence responses.
