           DNSSEC Trust Anchor Publication for the Root Zone
                  draft-jabley-dnssec-trust-anchor-16

Abstract

   The root zone of the Domain Name System (DNS) has been
   cryptographically signed using DNS Security Extensions (DNSSEC).

   In order to obtain secure answers from the root zone of the DNS using
   DNSSEC, a client must configure a suitable trust anchor.  This
   document describes the format and publication mechanisms IANA has
   used to distribute the DNSSEC trust anchors.

1.  Introduction

   The Domain Name System (DNS) is described in [RFC1034] and [RFC1035].
   Security extensions to the DNS (DNSSEC) are described in [RFC4033],
   [RFC4034], [RFC4035], [RFC4509], [RFC5155] and [RFC5702].

   A discussion of operational practices relating to DNSSEC can be found
   in [RFC6781].
