Abstract

The rapid diffusion of the Internet and development of high speed broadband networks have posed the problem of inadequate IPv4 address space on the Internet. Moreover, this lack of address space has been made worse by the progress made towards the ubiquitous network society, in which various types of information equipment, mobile computers and electrical appliances communicate on the internet. IPv6 was developed as a solution to this problem. In this paper I discussed various features provided by IPv6 over IPv4 in terms of improved security, lower administration cost, QoS options, mobility, auto configuration, and peer-to-peer capability etc. The transition mechanisms in use today are discussed in details. I have conducted a survey to point out current structure of three ISPs and how they can cope with the change and what will be the benefits for them in doing so. There are some limitations in this paper of course. But apart from those limitations I believe this paper will provide information which will be helpful in understanding the evolution, features and the transition of IPv6.

Chapter 1: Introduction

Executive Summery

This chapter outlines the main purpose of this research paper. Also it outlines the scope and the limitations of the research. The overview of internet protocol is illustrated as well in details.

1 Purpose of the Research

The main purpose of this research paper will be to discuss the evolution of Internet Protocol version 4 to Internet Protocol version 6. The focus will be to perform a research on various features provided by IPv6 and how it can be implemented using the existing IPv4 structure hence highlighting the different transition mechanisms. The benefits of the transition are endless and are illustrated in detail.
