Abstract

NSEC3 is a DNSSEC mechanism providing proof of nonexistence byasserting that there are no names that exist between two domain nameswithin a zone. Unlike its counterpart NSEC, NSEC3 avoids directlydisclosing the bounding domain name pairs. This document providesguidance on setting NSEC3 parameters based on recent operationaldeployment experience. This document updates RFC 5155 with guidanceabout selecting NSEC3 iteration and salt parameters.
