This document describes a method to generate negative answers from NSEC records for the special case of the DNS root. This improves performance; the resolver can answer immediatly, and does not need to query the root. It also cuts down on the so-called "junk" queries. [ Ed note: Text inside square brackets ([]) is additional background information, answers to frequently asked questions, general musings, etc. They will be removed before publication.] [ This document is being collaborated on in Github at: The most recent version of the document, open issues, etc should all be available here. The authors (gratefully) accept pull requests ]
