NSEC3 is a DNSSEC mechanism providing proof of nonexistence by
asserting that there are no names that exist between two domain names
within a zone.  Unlike its counterpart NSEC, NSEC3 avoids directly
disclosing the bounding domain name pairs.  This document provides
guidance on setting NSEC3 parameters based on recent operational
deployment experience.  This document updates RFC 5155 with guidance
about selecting NSEC3 iteration and salt parameters.

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