Abstract

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.
