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

Filename : draft-ietf-dnsop-nsec-aggressiveuse-01.txt
Pages : 12

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 resilience to DoS attacks, increases
performance / decreases latency, decreases resource utilization on
both authoritative and recursive servers, and also increases privacy.
This document updates RFC4035 by allowing resolvers to generate
negative answers based upon NSEC/NSEC3 records.
