This document describes how to construct DNSSEC NSEC resource records that cover a smaller range of names than called for by [-records]. By generating and signing these records on demand, authoritative name servers can effectively stop the disclosure of zone contents otherwise made possible by walking the chain of NSEC records in a signed zone.
