NSEC(1) General Commands Manual NSEC(1) NAME nsec -- generate NSEC records for a zone SYNOPSIS nsec [zonefile] DESCRIPTION nsec writes DNSSEC NSEC records for a zone to standard output.

It is used to fill in the gaps between the valid records in a zone and is returned alongside its signature in NX- DOMAIN responses to prove the absence of the requested record. OPTIONS None.
