Abstract

This document describes the global and other specialized IPv4 address blocks that have been assigned by the Internet Assigned Numbers Authority (IANA). It does not address IPv4 address space assigned to operators and users through the Regional Internet Registries. It also does not address allocations or assignments of IPv6 addresses or autonomous system numbers.

Abstract

   This document describes the global and other specialized IPv4 address

   blocks that have been assigned by the Internet Assigned Numbers

   Authority (IANA).  It does not address IPv4 address space assigned to

   operators and users through the Regional Internet Registries.  It

   also does not address allocations or assignments of IPv6 addresses or

   autonomous system numbers.

1. Introduction

   Throughout its entire history, the Internet has employed a central

   Internet Assigned Numbers Authority (IANA) responsible for the

   allocation and assignment of various identifiers needed for the

   operation of the Internet [RFC1174].  In the case of the IPv4 address

   space, the IANA allocates parts of the address space to Regional

   Internet Registries according to their established needs.  These

   Regional Internet Registries are responsible for the assignment of

   IPv4 addresses to operators and users of the Internet within their

   regions.

   Minor portions of the IPv4 address space have been allocated or

   assigned directly by the IANA for global or other specialized

   purposes.  These allocations and assignments have been documented in

   a variety of RFCs and other documents.  This document is intended to

   collect these scattered references.

   On an ongoing basis, the IANA has been designated by the IETF to make

   assignments in support of the Internet Standards Process [RFC2860].

   Section 4 of this document describes that assignment process.

2. Global and Other Specialized Address Blocks

   0.0.0.0/8 - Addresses in this block refer to source hosts on "this"

   network.  Address 0.0.0.0/32 may be used as a source address for this

   host on this network; other addresses within 0.0.0.0/8 may be used to

   refer to specified hosts on this network [RFC1700, page 4].

   10.0.0.0/8 - This block is set aside for use in private networks.

   Its intended use is documented in [RFC1918].  Addresses within this

   block should not appear on the public Internet.

   14.0.0.0/8 - This block is set aside for assignments to the

   international system of Public Data Networks [RFC1700, page 181]. The

   registry o...
