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 ietf@ietf.org mailing lists by 2017-03-27. Exceptionally, comments may be sent to iesg@ietf.org 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).
