Due to a combination of unfortunate wording in earlier documents,
aggressive use of NSEC and NSEC3 records may deny the existence of
names far beyond the intended lifetime of a denial. This document
changes the definition of the NSEC and NSEC3 TTL to correct that
situation. This document updates RFCs 4034, 4035, 5155, and 8198.

This document is a product of the Domain Name System Operations Working Group of the IETF.

This is now a Proposed Standard.

for improvements.  Please refer to the current edition of the Official
