1. Introduction

This paper provides an architecture and a plan for allocating IP

addresses in the Internet. This architecture and the plan are

intended to play an important role in steering the Internet towards

the Address Assignment and Aggregating Strategy outlined in [1].

The IP address space is a scarce shared resource that must be managed

for the good of the community. The managers of this resource are

acting as its custodians. They have a responsibility to the community

to manage it for the common good.

2. Scope

The global Internet can be modeled as a collection of hosts

interconnected via transmission and switching facilities. Control

over the collection of hosts and the transmission and switching

facilities that compose the networking resources of the global

Internet is not homogeneous, but is distributed among multiple

administrative authorities. Resources under control of a single

administration form a domain. For the rest of this paper, "domain"

and "routing domain" will be used interchangeably. Domains that

share their resources with other domains are called network service

providers (or just providers). Domains that utilize other domain's

resources are called network service subscribers (or just

subscribers). A given domain may act as a provider and a subscriber

simultaneously.

There are two aspects of interest when discussing IP address

allocation within the Internet. The first is the set of

administrative requirements for obtaining and allocating IP

addresses; the second is the technical aspect of such assignments,

having largely to do with routing, both within a routing domain

(intra-domain routing) and between routing domains (inter-domain

routing). This paper focuses on the technical issues.
