Updates to the Special-Purpose IP Address Registries
Abstract
This memo updates the IANA IPv4 and IPv6 Special-Purpose Address
Registries to address issues raised by the definition of a "global"
prefix. It also corrects several errors in registry entries to
ensure the integrity of the IANA Special-Purpose Address Registries.
This memo updates RFC 6890.

RFC 8190 Special-Purpose Address Registries June 2017
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) for link-local unicast
addresses.
Several issues have been raised with the documentation of some of the
special-purpose address blocks in [RFC6890]. Specifically, the
definition of "global" provided in [RFC6890] was misleading as it
slightly differed from the generally accepted definition of "global
scope" (i.e., the ability to forward beyond the boundaries of an
administrative domain, described as "global unicast" in the IPv6
addressing architecture [RFC4291]).
This memo updates the definition of "global" from [RFC6890] for the
IPv4 and IPv6 Special-Purpose Address Registries, augments the fields
contained within the registries in order to address the confusion
raised by the definition of "global", and corrects some errors in
some of the entries in the Special-Purpose Address Registries.
This memo updates [RFC6890].
2. IANA Considerations
2.1. Definition of Globally Reachable
[RFC6890] defined the term "global" without taking into consideration
the multiple uses of the term. Specifically, IP addresses can be
global in terms of allocation scope as well as global in terms of
routing/reachability. To address this ambiguity, the use of the term
