Abstract

The PIER [Procedures for Internet/Enterprise Renumbering] working group is compiling a series of documents to assist and instruct organizations in their efforts to renumber. However, it is becoming apparent that, with the increasing number of new Internet Service Providers (ISP's) and organizations getting connected to the Internet for the first time, the concept of network renumbering needs to be further defined. This document attempts to clearly define the concept of network renumbering and discuss some of the more pertinent reasons why an organization would have a need to do so.

1. Introduction

The popularity of connecting to the global Internet over the course

of the past several years has spawned new problems; what most people

casually refer to as "growing pains" can be attributed to more basic

problems in understanding the requirements for Internet connectivity.

However, the reasons why organizations may need to renumber their

networks can greatly vary. We'll discuss these issues in some amount

of detail below. It is not within the intended scope of this

document to discuss renumbering methodologies, techniques, or tools.

2. Background

The ability for any network or interconnected devices, such as

desktop PCs or workstations, to obtain connectivity to any potential

destination in the global Internet is reliant upon the possession of

unique IP host addresses [1]. A duplicate host address that is being

used elsewhere in the Internet could best be described as

problematic, since the presence of duplicate addresses would cause

one of the destinations to be unreachable from some origins in the

Interne...
