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.
For the definition of Status, see RFC 2026.
For the definition of Stream, see RFC 8729.
