Internet-Draft              IANA RPKI Objects                   May 2011


2.  Introduction

   An Infrastructure to Support Secure Internet Routing
   [I-D.ietf-sidr-arch] directs IANA [RFC2860] to issue Resource Public
   Key Infrastructure (RPKI) objects for which it is authoritative.
   This document describes the objects IANA will issue.  If IANA is
   directed to issue additional RPKI objects in future, this document
   will be revised and a new version issued.

   The signed objects described here that IANA will issue are the
   unallocated, reserved, special use IPv4 and IPv6 address blocks, and
   the unallocated and reserved Autonomous System numbers.  These number
   resources are managed by IANA for the IETF, and thus IANA bears the
   responsibility of issuing the corresponding RPKI objects.  The reader
   is encouraged to consider the technical effects on the public routing
   system of the signed object issuance proposed for IANA in this
   document.

   This document does not deal with BGP [RFC4271] routing systems as
   those are under the policy controls of the organizations that operate
   them.  Readers are directed to Local Trust Anchor Management for the
   Resource Public Key Infrastructure [I-D.ietf-sidr-ltamgmt] for a
   description of how to locally override IANA issued objects, e.g. to
   enable use of unallocated, reserved, and special use IPv4 and IPv6
   address blocks in a local context.

   The direction to IANA contained herein follows the ideal that it
   should represent the ideal technical behavior for registry, and
   related registry, actions.

Internet-Draft              IANA RPKI Objects                   May 2011


3.  Required Reading

   Readers should be familiar with the RPKI, the RPKI Repository
   Structure, and the various RPKI objects, uses and interpretations
   described in the following: [I-D.ietf-sidr-arch],
   [I-D.ietf-sidr-res-certs], [I-D.ietf-sidr-roa-format],
   [I-D.ietf-sidr-ghostbusters], [I-D.ietf-sidr-ltamgmt],
   [I-D.ietf-sidr-roa-validation], [I-D.ietf-sidr-usecases],
   [I-D.ietf-sidr-cp], and [I-D.ietf-sidr-rpki-manifests].

   NOTE: The addresses used in this document are not example addresses
   therefore they are not compliant with [RFC3849], [RFC5735], and
   [RFC5771].  This is intentional as the practices described in this
   document are directed to specific instances of real world addresses.

Internet-Draft              IANA RPKI Objects                   May 2011


4.  Definitions

   Internet Number Resources (INR): The number identifiers for IPv4
   [RFC0791] and IPv6 [RFC2460] addresses, and for Autonomous Systems.

   IANA: Internet Assigned Numbers Authority (a traditional name, used
   here to refer to the technical team making and publishing the
   assignments of Internet protocol technical parameters).  The
   technical team of IANA is currently a part of ICANN [RFC2860].

   RPKI: Resource Public Key Infrastructure.  A Public Key
   Infrastructure designed to provide a secure basis for assertions
   about holdings of Internet numeric resources.  Certificates issued
   under the RPKI contain additional attributes that identify IPv4,
   IPv6, and Autonomous System Number (ASN) resources
   [I-D.ietf-sidr-arch].

   ROA: Route Origination Authorization.  A ROA is an RPKI object that
   enables the holder of the address prefix to specify an AS that is
   permitted to originate (in BGP) routes for that prefix
   [I-D.ietf-sidr-roa-format].

   AS0 ROA: A ROA containing a value of 0 in the ASID field.  Validation
   of Route Origination using the Resource Certificate  PKI and ROAs
   [I-D.ietf-sidr-roa-validation] states "A ROA with a subject of AS0
   (AS0-ROA) is an attestation by the holder of a prefix that the prefix
   described in the ROA, and any more specific prefix, should not be
   used in a routing context."

   "Not intended to be (publicly) routed": This phrase refers to
   prefixes that are not meant to be represented in the global Internet
   routing table (for example 192.168/16, [RFC1918]).

Internet-Draft              IANA RPKI Objects                   May 2011


5.  Reserved Resources

   Reserved IPv4 and IPv6 resources are held back for various reasons by
   IETF action.  Generally such resources are not intended to be
   globally routed.  An example of such a reservation is 127.0.0.0/8
   [RFC5735].  See Appendix A (Appendix A) and B (Appendix B) for IANA
   reserved resources.

   IANA SHOULD issue an AS0 ROA for all reserved IPv4 and IPv6 resources
   not intended to be routed.  The selection of the [RFC2119]
   terminology is intentional as there may be situations where the ASO
   ROA is removed or not issued prior to an IANA registry action.  It is
   not appropriate to place IANA into a situation where, through normal
   interal operations, its bahavior contradicts IETF standards.

   There are a small number of reserved resources that are intended to
   be routed, for example 192.88.99.0/24 [RFC3068].  See Appendix A
   (Appendix A) and B (Appendix B) for IANA reserved resources.

   IANA MUST NOT issue any ROAs (AS0 or otherwise) for reserved
   resources that are expected to be globally routed.

6.  Unallocated Resources

   Internet Number Resources that have not yet been allocated for
   special purposes [RFC5736], to Regional Internet Registries (RIRs),
   or to others are considered as not intended to be globally routed.

   IANA SHOULD issue an AS0 ROA for all Unallocated Resources.  The
   selection of the [RFC2119] terminology is intentional as there may be
   situations where the ASO ROA is removed or not issued prior to an
   IANA registry action.  It is not appropriate to place IANA into a
   situation where, through normal interal operations, its bahavior
   contradicts IETF standards.

7.  Special Purpose Registry Resources

   Special Registry Resources [RFC5736] fall into one of two categories
   in terms of routing.  Either the resource is intended to be seen in
   the global Internet routing table in some fashion, or it isn't.  An
   example of a special purpose registry INR that is intended for global
   routing is 2001:0000::/32 [RFC4380].  An example of an INR not
   intended to be seen would be 2001:002::/48 [RFC5180].

   IANA MUST NOT issue any ROAs (AS0 or otherwise) for Special Purpose
   Registry Resources that are intended to be globally routed.

   IANA SHOULD issue an AS0 ROA for Special Purpose Registry Resources
   that are not intended to be globally routed.

8.  Multicast

   Within the IPv4 Multicast [RFC5771] and IPv6 Multicast [RFC4291]
   registries there are a number of Multicast registrations that are not
   intended to be globally routed.

   IANA MUST issue an AS0 ROA covering the following IPv4 and IPv6
   multicast INRs:


   IPv4:
           - Local Network Control Block
              224.0.0.0 - 224.0.0.255 (224.0.0/24)
           - IANA Reserved portions of RESERVED
              224.1.0.0-224.1.255.255 (224.1/16)
           - RESERVED
              224.5.0.0-224.251.255.255 (251 /16s)
              225.0.0.0-231.255.255.255 (7 /8s)

   IPv6:
           - Node-Local Scope Multicast Addresses
           - Link-Local Scope Multicast Addresses

   IANA MUST NOT issue any ROAs (AS0 or otherwise) for any other
   multicast addresses unless directed by an IESG approved standards
   track document with an appropriate IANA Considerations section.

9.  Informational Objects

   One informational object that can exist at a publication point of an
   RPKI repository is the Ghostbusters Record
   [I-D.ietf-sidr-ghostbusters].

   IANA MUST issue a ghostbusters object appropriate in content for the
   resources IANA maintains.

10.  Certificates and CRLs

   Before IANA can issue a ROA it MUST first establish an RPKI
   Certification Authority (CA) that covers unallocated, reserved, and
   special use INRs.  A CA that covers these INRs MUST contain contain
   RFC 3379 extensions [RFC3779] for those corresponding number
   resources in its Certificate.  This CA MUST issue single-use End
   Entity (EE) certificates for each ROA that it generates.  The EE
   certificate will conform to the Resource Certificate Profile
   [I-D.ietf-sidr-res-certs] and the additional constraints specified in
   [I-D.ietf-sidr-roa-format].  IANA MUST maintain a publication point
   for this CA's use and MIUST publish manifests
   [I-D.ietf-sidr-rpki-manifests] (with its corresponding EE
   certificate) for this publication point.  IANA MUST issue a
   Certificate Revocation List (CRL) under this CA certificate for the
   EE certificates noted above.  All objects issued by this CA will
   conform to the RPKI Certificate Policy [I-D.ietf-sidr-cp].

11.  IANA Considerations

   This document directs IANA to issue, or refrain from issuing, the
   specific RPKI objects described here for the current set of reserved,
   unallocated, and special registry Internet Number Resources.  Further
   IANA MUST notify all other INR registries that RPKI objects have been
   issued for the Internet Number Resources described in this document
   to avoid the potential for issuance of duplicate objects that might
   confuse relying parties.

   that already discussed in SIDR-WG documents.
