Title : Aggressive use of NSEC/NSEC3
Authors : Kazunori Fujiwara

Filename : draft-ietf-dnsop-nsec-aggressiveuse-02.txt
Pages : 13

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 generate negative answers within a
range. 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 resolvers to generate
negative answers based upon NSEC/NSEC3 records.
