Abstract

This RFC describes methods to preserve IP address space by not allocating globally unique IP addresses to hosts private to an enterprise while still permitting full network layer connectivity between all hosts inside an enterprise as well as between all public hosts of different enterprises. The authors hope, that using these methods, significant savings can be made on allocating IP address space.

                Address Allocation for Private Internets

Status of this Memo

   This memo provides information for the Internet community.  This memo
   does not specify an Internet standard of any kind.  Distribution of
   this memo is unlimited.

1. Introduction

   This RFC describes methods to preserve IP address space by not
   allocating globally unique IP addresses to hosts private to an
   enterprise while still permitting full network layer connectivity
   between all hosts inside an enterprise as well as between all public
   hosts of different enterprises. The authors hope, that using these
   methods, significant savings can be made on allocating IP address
   space.

   For the purposes of this memo, an enterprise is an entity
   autonomously operating a network using TCP/IP and in particular
   determining the addressing plan and address assignments within that
   network.

2. Motivation

   With the proliferation of TCP/IP technology worldwide, including
   outside the Internet itself, an increasing number of non-connected
   enterprises use this technology and its addressing capabilities for
   sole intra-enterprise communications, without any intention to ever
   directly connect to other enterprises or the Internet itself.

   The current practice is to assign globally unique addresses to all
   hosts that use TCP/IP.  There is a growing concern that the finite IP
   address space might become exhausted.  Therefore, the guidelines for
   assigning IP address space have been tightened in recent years [1].
   These rules are often more conservative than enterprises would like,
   in order to implement and operate their networks.
