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.

Abstract

   This document was submitted to the IETF IPng area in response to RFC
   1550.  Publication of this document does not imply acceptance by the
   IPng area of any ideas expressed within.  Comments should be
   submitted to the  mailing list.

   This memo describes a proposal made to to the Routing and Addressing
   group [ROAD] January 1992 by Robert Hinden.  It was originally sent
   as an email message.  It proposes a medium term solution to the
   Internet's routing and addressing problems.

INTRODUCTION

   I would like to propose a new scheme which I believe is a good medium
   term solution to the routing and address problems of the internet.
   It has the following positive attributes:

      - No Changes to Hosts
      - No Changes to Most Routers
      - No New Routing Protocols
      - No New Internet Protocols
      - No Translation of Addresses in Packets
      - Reduces the Routing Table Size in All Routers
      - Uses the Current Internet Address Structure

   It is not a solution good for all time, because it does impose some
   size limits and does not support new internet services such as
   guaranteed bandwidth, delay, etc.  It does require border routers to
   do additional processing, but does not require any packet
   translation.  I believe that this scheme will give us enough time to
   put into place a long term solution (i.e. pick one or more of CLNP,
   *NAT, IDPR, IDRP, Nimrod, Unified, NewIP, etc.)
