   This document has been reviewed by the Federal Engineering Task Force
   (FEPG) on behalf of the Federal Networking Council (FNC), the co-
   chairs of the International Engineering Planning Group (IEPG), and
   the Reseaux IP Europeens (RIPE).  There was general consensus by
   those groups to support the recommendations proposed in this document
   for management of the IP address space.

1.0  Introduction

   With the growth of the Internet and its increasing globalization,
   much thought has been given to the evolution of the network number
   allocation and assignment process. RFC 1174, "Identifier Assignment
   and Connected Status", dated August 1990 recommends that the Internet
   Registry (IR) continue as the principal registry for network numbers;
   however, the IR may allocate blocks of network numbers and the
   assignment of those numbers to qualified organizations.  The IR will
   serve as the default registry in cases where no delegated
   registration authority has been identified.

   The distribution of the registration function is desirable, and in
   keeping with that goal, it is necessary to develop a plan which
   manages the distribution of the network number space.  The demand for
   network numbers has grown significantly within the last two years and
   as a result the allocation of network numbers must be approached in a
   more systematic fashion.

   This document proposes a plan which will forward the implementation
   of RFC 1174 and which defines the allocation and assignment of the
   network number space.  There are three major topics to be addressed:

      1) Qualifications for Distributed Regional Registries

      2) Allocation of the Network Number Space by the Internet Registry

      3) Assignment of the Network Numbers

2.0  Qualifications for Distributed Regional Registries

   The major reason to distribute the registration function is that the
   Internet serves a more diverse global population than it did at its
   inception.  This means that registries which are located in distinct
   geographic areas may be better able to serve the local community in
   terms of language and local customs. While there appears to be wide
   support for the concept of distribution of the registration function,
   it is important to define how the candidate delegated registries will
   be chosen and from which geographic areas.

   Based on the growth and the maturity of the Internet in Europe,
   Central/South America and the Pacific Rim areas, it is desirable to
   consider delegating the registration function to an organization in
   each of those geographic areas.  Until an organization is identified
   in those regions, the IR will continue to serve as the default
   registry.  The IR remains the root registry and continues to provide
   the registration function to all those regions not covered by
   distributed regional registries.  And as other regions of the world
   become more and more active in the Internet, the IANA and the IR may
   choose to look for candidate registries to serve the populations in
   those geographic regions.

   It is important that the regional registry is unbiased and and widely
   recognized by network providers and subscribers within the geographic
   region.  It is also important that there is just a single regional
   registry per geographical region at this level to provide for
   efficient and fair sub-allocation of the address space.  To be
   selected as a distributed regional registry an organization should
   meet the following criteria:

      a) networking authorities within the geographic area
         legitimize the organization

      b) the organization is well-established and has
         legitimacy outside of the registry function

      c) the organization will commit appropriate resources to
         provide stable, timely, and reliable service
         to the geographic region

      d) the commitment to allocate IP numbers according to
         the guidelines established by the IANA and the IR

      e) the commitment to coordinate with the IR to establish
         qualifications and strategies for sub-allocations of
