Subject: Last Call: <draft-ietf-dnsop-nsec-aggressiveuse-08.txt> (Aggressive use of DNSSEC-validated Cache) to Proposed Standard

From: The IESG <[email-masked]>
Date: Mon, 13 Mar 2017 08:52:44 -0700

The IESG has received a request from the Domain Name System Operations WG
(dnsop) to consider the following document:
- 'Aggressive use of DNSSEC-validated Cache'
  <draft-ietf-dnsop-nsec-aggressiveuse-08.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
[email-masked] mailing lists by 2017-03-27. Exceptionally, comments may be
sent to [email-masked] instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.

Abstract

   The DNS relies upon caching to scale; however, the cache lookup
   generally requires an exact match.  This document specifies the use
   of NSEC/NSEC3 resource records to allow DNSSEC validating resolvers
   to generate negative answers within a range, and positive answers
   from wildcards.  This increases performance / decreases latency,
   decreases resource utilization on both authoritative and recursive
   servers, and also increases privacy.  It may also help increase
   resilience to certain DoS attacks in some circumstances.

   This document updates RFC4035 by allowing validating resolvers to
   generate negative answers based upon NSEC/NSEC3 records (and positive
   answers in the presence of wildcards).
