INTERNET REGISTRY IP ALLOCATION GUIDELINES
Status of this Memo
This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for
improvements. Distribution of this memo is unlimited.
IESG Note:
By approving this document as a Best Current Practice,the IESG
asserts its belief that this policy described herein is an accurate
representation of the current practice of the IP address registries
with respect to address assignment. This does not constitute
endorsement or recommendation of this policy by the IESG. The IESG
will reevaluate its approval of this document in December 1997 taking
into consideration the results of the discussions that will be take
place in the IRE Working Group between now and then.
Abstract
This document describes the registry system for the distribution of
globally unique Internet address space and registry operations.
Particularly this document describes the rules and guidelines
governing the distribution of this address space.
This document describes the IP assignment policies currently used by
the Regional Registries to implement the guidelines developed by the
IANA. The guidelines and these policies are subject to revision at
the direction of the IANA. The registry working group (IRE WG) will
be discussing these issues and may provide advice to the IANA about
possible revisions.
This document replaces RFC 1466, with all the guidelines and
procedures updated and modified in the light of experience.

RFC 2050 Internet Registry IP Allocation Guidelines November 1996
This document does not describe private Internet address space and
multicast address space. It also does not describe regional and
local refinements of the global rules and guidelines.
This document can be considered the base set of operational
guidelines in use by all registries. Additional guidelines may be
imposed by a particular registry as appropriate.

1. Introduction
The addressing constraints described in this document are largely the
result of the interaction of existing router technology, address
assignment, and architectural history. After extensive review and
discussion, the authors of this document, the IETF working group that
reviewed it and the IESG have concluded that there are no other
currently deployable technologies available to overcome these
limitations. In the event that routing or router technology develops
to the point that adequate routing aggregation can be achieved by
other means or that routers can deal with larger routing and more
dynamic tables, it may be appropriate to review these constraints.
Internet address space is distributed according to the following
three goals:
1) Conservation: Fair distribution of globally unique Internet address
space according to the operational needs of the end-users and Internet
