The IESG has received a request from the Domain Name System Operations WG (dnsop) to consider the following document: - 'NSEC and NSEC3 TTLs and NSEC Aggressive Use' <draft-ietf-dnsop-nsec-ttl-04.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the last-call@ietf.org mailing lists by 2021-05-04. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Due to a combination of unfortunate wording in earlier documents, aggressive use of NSEC and NSEC3 records may deny 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 RFC 4034, RFC 4035, RFC 5155, and RFC 8198. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-dnsop-nsec-ttl/ No IPR declarations have been submitted directly on this I-D.
