Introduction 75 In order to support new protocols and practices, the IETF 76 occasionally reserves an address block a for special purpose. For 77 example, [RFC1122] reserves an IPv4 address block (0.0.0.0/8) to 78 represent the local (i.e., "this") network. Likewise, [RFC4291] 79 reserves an IPv6 address block (fe80::/10) to represent link-scoped 80 unicast addresses. 82 Periodically, the IETF publishes an RFC that catalogs special-purpose 83 address blocks. Currently, [RFC5735] catalogs all IPv4 special- 84 purpose address blocks and [RFC5156] catalogs all IPv6 special- 85 purpose address blocks. 87 [RFC5736] assigns an IPv4 address block (192.0.0.0/24) to IANA and 88 instructs IANA to allocate special-purpose address blocks from this 89 space. [RFC5736] also instructs IANA to create an IPv4 Special- 90 Purpose Address Registry that records allocations from this address 91 space. However, [RFC5736] does not instruct IANA to record special- 92 purpose address block reservations from outside of the aforementioned 93 space in the IPv4 Special-Purpose Address Registry. 95 Likewise, [RFC2928] assigns an IPv6 address block (2001:0000::/23) to 96 IANA and instructs IANA to allocate special-purpose address blocks 97 from this space. [RFC4773] instructs IANA to create an IPv6 Special- 98 Purpose Address Registry that records allocations from this address 99 space. However, [RFC4773] does not instruct IANA to record special- 100 purpose address block reservations from outside of the aforementioned 101 space in the IPv6 Special-Purpose Address Registry. 103 This memo instructs IANA to restructure its IPv4 and IPv6 Special- 104 Purpose Address Registries. Therefore, this document updates 105 [RFC5736] and [RFC4773] which define the current structure of the 106 aforementioned registries. 108 Specifically, this memo instructs IANA to record all special-purpose 109 address blocks in the aforementioned registries. These include, but 110 are not limited to, IPv4 allocations from 192.0.0.0/24 and IPv6 111 allocations from 2001:0000::/23. When the aforementioned registries 112 include all special-purpose address blocks, [RFC5735] and [RFC5156] 113 will become redundant with the registries. Therefore, this memo 114 obsoletes [RFC5735] and [RFC5156]. 116 Furthermore, this memo defines: 118 o a common set of information that the registries will maintain 119 regarding each special-purpose address block 121 o a common set of requirements for future entries 123 2. IANA Considerations 125 IANA will restructure the following registries: 127 o IPv4 Special-Purpose Address Registry 129 o IPv6 Special-Purpose Address Registry 131 The IPv4 Special-Purpose Address Registry will record all IPv4 132 special-purpose address blocks. These reservations will include, but 133 not be limited to, allocations from the 192.0.0.0/24 address block. 134 Likewise, the IPv6 Special-Purpose Address Registry will record all 135 IPv6 special-purpose address blocks. These reservations will 136 include, but not be limited to, allocations from the 2001:0000::/23 137 address block. 139 Section 2.1 of this document describes information that both 140 registries will maintain for each entry. Initially, IANA will 141 populate the IPv4 Special-Purpose Address Registry with information 142 taken from Section 2.2 of this document. Likewise, IANA will 143 populate the IPv6 Special-Purpose Address Registry with information 144 taken from Section 2.3 of this document. 146 IANA will update the aforementioned registries as requested in the 147 "IANA Considerations" section of an IESG-reviewed document. The " 148 IANA Considerations" section must include all of the information 149 specified in Section 2.1 of this document. 151 2.1. Information Requirements 153 The IPv4 and IPv6 Special-Purpose Address Registries will maintain 154 the following information regarding each entry: 156 o Prefix - An IPv4 or IPv6 prefix that identifies the special- 157 purpose address block 159 o Name - A descriptive name for the special-purpose address block 161 o RFC - The RFC though which the special-purpose address block was 162 requested 164 o Allocation Date - The date upon which the special purpose address 165 block was allocated 167 o Termination Date - The date upon which the allocation is to be 168 terminated. This field is applicable for limited-use allocations 169 only. 171 o Source - A boolean value indicated whether an address from the 172 allocated special-purpose address block is valid when used as the 173 source address of an IP datagram that transits two devices 175 o Destination - A boolean value indicated whether an address from 176 the allocated special-purpose address block is valid when used as 177 the destination address of an IP datagram that transits two 178 devices 180 o Routable - A boolean value indicating whether a IP datagram whose 181 destination address is drawn from the allocated special-purpose 182 address block is routable (i.e., may traverse more than a single 183 IP interface) 185 o Global - A boolean value indicating whether a IP datagram whose 186 destination address is drawn from the allocated special-purpose 187 address block is routable beyond a specified administrative 188 domain. 190 If the value of "Destination" is FALSE, the values of "Routable" and 191 "Global" must also be false. 193 2.2.

Security Considerations 693 Security of the Internet's routing system relies on the ability to 694 authenticate an assertion of unique control of an address block. 695 Measures to authenticate such assertions rely on validation that the 696 address block forms part of an existing allocated address block, and 697 that there is a trustable and unique reference in the IANA address 698 registries. 700 The proposed registry is intended to provide an authoritative source 701 of information regarding the currency and intended purpose of special 702 purpose address blocks that are designated from the IANA-administered 703 Special Purpose registry. This is a small step towards the creation 704 of a comprehensive registry framework that can be used as a trust 705 point for commencing a chain of address validation. Consideration 706 should be given to IANA registry publication formats that are machine 707 parseable, and also the use of file signatures and associated 708 certificate mechanisms to allow applications to confirm that the 709 registry contents are current, and that they have been published by 710 the IANA. 712 4.
