1. Introduction
In order to support new protocols and practices, the IETF
occasionally reserves an address block for a special purpose. For
example, [RFC1122] reserves an IPv4 address block (0.0.0.0/8) to
represent the local (i.e., "this") network. Likewise, [RFC4291]
reserves an IPv6 address block (fe80::/10) to represent link-scoped
unicast addresses.
The current list of all special-purpose address blocks are described
in [RFC6890]. However, several issues have been raised with how
"global" is defined in that document. Specifically, the definition
of global provided in [RFC6890] focuses on the prefix's ability to be
routed globally within the Internet and does not indicate if the
prefix is globally scoped (i.e., may be routed beyond the local link;
described as "global unicast" in the IPv6 addressing architecture
[RFC4291]).
This memo reiterates the assignments made to the IPv4 and IPv6
Special-Purpose Address Registries and augments the fields contained
within the registires in order to address the confusion raised by the
definition of "global". Furthermore, this memo defines:
o a common set of information that the registries will maintain
regarding each special-purpose address block

o a common set of requirements for future entries
This memo obsoletes [RFC6890].
2. IANA Considerations
2.1. Assignment of an IPv4 Address Block to IANA
Table 7 of this document records the assignment of an IPv4 address
block (192.0.0.0/24) to IANA for IETF protocol assignments. This
address allocation to IANA is intended to support IETF protocol
assignments. A more general view of the roles of IANA with respect
to address allocation functions is documented in Sections 4.1 and 4.3
[RFC2860].
IANA has designated special-purpose address blocks in compliance with
[RFC2860].
2.2. Restructuring of the IPv4 and IPv6 Special-Purpose Address
Registries
IANA has restructured the following registries:
IPv4 Special-Purpose Address Registry
IPv6 Special-Purpose Address Registry
The IPv4 Special-Purpose Address Registry records all IPv4 special-
purpose address blocks. These reservations include, but are not
limited to, allocations from the 192.0.0.0/24 address block.
Likewise, the IPv6 Special-Purpose Address Registry records all IPv6
special-purpose address blocks. These reservations include, but are
not limited to, allocations from the 2001:0000::/23 address block,
which is a globally scoped address block.
Section 2.2.1 of this document describes information that both
registries will maintain for each entry. IANA has populated the IPv4
Special-Purpose Address Registry with information taken from
Section 2.2.2 of this document. Likewise, IANA has populated the
IPv6 Special-Purpose Address Registry with information taken from
Section 2.2.3 of this document.
IANA will update the aforementioned registries as requested in the
"IANA Considerations" section of a document that has passed IETF
Review [RFC5226]. The "IANA Considerations" section MUST include all
of the information specified in Section 2.2.1 of this document.

2.2.1. Information Requirements
The IPv4 and IPv6 Special-Purpose Address Registries maintain the
following information regarding each entry:
Address Block - A block of IPv4 or IPv6 addresses that has been
registered for a special purpose.
Name - A descriptive name for the special-purpose address block.
RFC - The RFC through which the special-purpose address block was
requested.
Allocation Date - The date upon which the special-purpose address
block was allocated.
Termination Date - The date upon which the allocation is to be
terminated. This field is applicable for limited-use allocations
only.
Source - A boolean value indicating whether an address from the
allocated special-purpose address block is valid when used as the
source address of an IP datagram that transits two devices.
Destination - A boolean value indicating whether an address from
the allocated special-purpose address block is valid when used as
the destination address of an IP datagram that transits two
devices.
Forwardable - A boolean value indicating whether a router may
forward an IP datagram whose destination address is drawn from the
allocated special-purpose address block between external
interfaces.
Globally Reachable - A boolean value indicating whether an IP
datagram whose destination address is drawn from the allocated
special-purpose address block is forwardable beyond a specified
administrative domain.
Reserved-by-Protocol - A boolean value indicating whether the
special-purpose address block is reserved by IP, itself. This
value is "TRUE" if the RFC that created the special-purpose
address block requires all compliant IP implementations to behave
in a special way when processing packets either to or from
addresses contained by the address block.
If the value of "Destination" is FALSE, the values of "Forwardable"
and "Globally Reachable" must also be false.

3. Security Considerations
Security of the Internet's routing system relies on the ability to
authenticate an assertion of unique control of an address block.
Measures to authenticate such assertions rely on validation that the
address block forms part of an existing allocated address block and
that there is a trustable and unique reference in the IANA address
registries.
The proposed registry is intended to provide an authoritative source
of information regarding the currency and intended purpose of special
purpose address blocks that are designated from the IANA-administered
Special-Purpose registry. This is a small step towards the creation
of a comprehensive registry framework that can be used as a trust
point for commencing a chain of address validation. Consideration
should be given to IANA registry publication formats that are machine
parsable. Additionally, consideration should be given to the use of
file signatures and associated certificate mechanisms to allow
applications to confirm that the registry contents are current and
that they have been published by the IANA.
