Abstract:
While DNS highly depends on cache, its cache usage of non-existence
information was limited to exact matching. This draft proposes the
aggressive use of a NSEC/NSEC3 resource record, which is able to
express non-existence of range of names authoritatively. With this
proposal, shorter latency to many of negative responses is expected
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.
