Abstract:
While DNS highly depends on cache, its cache usage of non-existence
information has been limited to exact matching. This draft proposes
the aggressive use of a NSEC/NSEC3 resource record, which is able to
express non-existence of a range of names authoritatively. With this
proposal, it is expected that shorter latency to many of negative
responses as well as some level of mitigation of random sub-domain
attacks (referred to as "Water Torture" attacks). It is also
expected that non-existent TLD queries to Root DNS servers will
decrease.
