Description

Very nice feature for DNS optimization, which can reduce the number of queries to authoritative name servers.
See https://tools.ietf.org/html/rfc8198

unbound.conf(5):

aggressive-nsec: <yes or no>
              Aggressive  NSEC uses the DNSSEC NSEC chain to synthesize NXDOMAIN and other denials, using information from previous
              NXDOMAINs answers.  Default is no.  It helps to reduce the query rate towards targets that get a very  high  nonexis‐
              tent name lookup rate.
