Title : Aggressive use of NSEC/NSEC3

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 based upon NSEC/NSEC3 records (and positive answers
in the presence of wildcards).
