The definitive guide to IPv6 decision making for non-technical business leaders


Every year, organizations rely on Internet applications and services more deeply—and every year, Internet infrastructure grows more powerful and complex. As the limitations of traditional IPv4 addressing become increasingly apparent, many decision makers recognize that a transition to IPv6 is needed far sooner than anticipated. Global IPv6 Strategies gives non-technical decision makers the information to plan and execute an orderly, efficient migration to IPv6—and reap the business benefits.


This book’s authors offer practical scenarios, proven best practices, and real-world case studies drawn from their unsurpassed experience helping enterprises and service providers move to IPv6. Writing for non-technical decision makers, they systematically review the costs, benefits, impacts, and opportunities associated with IPv6 migration. Their insights and strategies can help you address both the technical side of IPv6 and the rarely discussed organizational issues that can make or break your transition.


Patrick Grossetete, manager of Product Management at Cisco®, is responsible for key Cisco IOS® software technologies including IPv6 and IP Mobility. A member of the IPv6 Forum Technical Directorate, he has been honored with the IPv6 Forum Internet Pioneer Award.

The continued evolution and operation of the Internet as a truly global asset faces multiple challenges: impending exhaustion of the global IPv4 address space, new operating systems and applications, next generation infrastructures, and demand for always-on connectivity for a growing variety of devices. The requirements of a new Internet, the pressure generated by the lack of resources for the existing one, and government mandates are just a few drivers for the soaring interest in IPv6 and the demand for information related to the protocol. The technological aspects of the next generation Internet protocol have been diligently covered through a wide range of publications. Considering, the potential implications of early versus late IPv6 adoption, there is significant interest in information related to adoption strategies, to business perspectives on IPv6 use, and to concrete experiences.

The global impact of a technology or a set of technologies on the larger population and the society as a whole can truly be evaluated years after its creation when enough data has been accumulated for a proper analysis. As an example, the unprecedented, wide range of advances made in all domains of life (arts, education, politics, philosophy, literature, and science) during the Renaissance period, one of the most prolific periods in human history, can be traced to the adoption of one technology: printing. Gutenberg's invention increased the amount of documented knowledge and information by reducing the costs of capturing it. More importantly, printing dramatically increased accessibility to knowledge and information by reducing the replication costs. One technology enabled human civilization to build its knowledge base and to tap into a significantly larger pool of talent. These scaled-up resources were the information and communication infrastructure that enabled innovations in all aspects of human life.

In itself, the "moveable type" technology, as Gutenberg called it, was not the prize but just the enabler. Gutenberg's enterprise defaulted shortly after a promising start but it enabled an information revolution that was the catalyst of many other revolutions. The often drawn parallel between the discovery and history of printing and that of the Internet highlights the same characteristic. The Internet represents the enabler of today's information revolution, changing the way we live, play, learn, and work.

A close evaluation of the two information revolutions highlights a very important difference. The printing-based revolution was to a certain extent asymmetric—it somewhat reduced the cost of producing content while it vastly reduced the cost of accessing content. This paradigm was further supported and expanded in scope through other media means such as radio and television. Although in its initial implementation stages the Internet appeared to do the same thing, as it matured, it enabled a more symmetric information revolution by dramatically decreasing the costs of producing content. The Internet is reducing the costs of producing and consuming information, and bringing together enough users to create an audience for any niche content. In addition, the Internet is providing its users with ubiquitous global access to information, removing the distance and time barriers faced in the past. The Internet has laid the foundation for a new and different information revolution. While traditional media such as newspaper, radio, and television cater to the mainstream, the Internet addresses new audiences and enables new means of communications and new business models.

It is important to make a clear distinction between the Internet and the applications that run over it. These applications are apparent to most of its users and are the true measure of the economic and societal impact of the Internet. With the exception of technologists, however, the terms Internet (infrastructure) and World Wide Web (application) are for most people interchangeable. While like many other technologies such as railroads, automobiles, and radio, the Internet inspired its own economic bubble, it survives, continues to grow, and provides the environment for truly valuable applications and services. This infrastructure and its evolution is the focus of this book despite the necessary references to its uses.

From its initial deployment as a research network to its current state, the Internet as an infrastructure has seen the functionality of the devices, applications, and services deployed on it grow in direct relation to its capabilities, capacity, and scale:

Higher speeds: The Internet is leveraging newer technologies providing wired or wireless access with ever-increasing bandwidths and lower costs.

  • Larger footprint: The "network of networks," as the Internet is known, continues to expand its geographical coverage and to include more and more businesses and people.

  • Including more device types: The Internet evolved from interconnecting large mainframes with dumb terminals to connecting personal computers, mobile phones, and sensors.

  • Always-on connectivity: Ubiquitous in nature, the Internet enables its users to communicate continuously regardless of their point of attachment.

To support Web 2.0, which encompasses the latest set of Internet-based applications and services, the infrastructure continues to evolve through the so-called Next Generation Networks. Web 2.0 is finally taking advantage of the Internet's true potential and distances by its immediate "people-to-people" collaborative environment from the technologies that expanded the information revolution started by printing. Web 2.0 is starting the next information revolution, and for that it requires an ever-increasing user base, individually addressable users, and symmetric (similar upstream and downstream bandwidth), always-on, mobile connections. Will the technology be able to cope with these demands?

Although today nobody could envisage a world without Internet connectivity, the original design of the Internet Protocol, the foundation of this infrastructure, did not foresee this level of adoption. IP simply does not have the resources to connect today's earth population let alone to support its growth over the coming years. Moreover, in an attempt to conserve resources, the Internet today lost the symmetry of its original brilliant design. This is why the time is high for a new version of the Internet Protocol, known as IPv6, a necessary evolution for this mature technology.

As is the case with any foundational, infrastructure technology, the importance and economic impact of this evolution might be difficult to measure. Although the upgrade is an inevitable process, misunderstanding its importance and delaying its planning and adoption can have a significant impact at micro- and macroeconomic levels. This is particularly the case with infrastructure technologies that benefit from very little attention from a market driven mostly by short-term delivery. The right perspective on the evolution of the infrastructure needs to be bootstrapped by strategic, global, and visionary thinking. On January 16, 2003, the National Infrastructure Advisory Council (NIAC) was presented an IPv6 strawman proposal by John Chambers, who at the time was one of its members. In his letter to the council, Chambers stated:

We believe the United States needs a migration strategy built on a solid investigation of the issues surrounding IPv6 adoption, and therefore propose that the United States National Infrastructure Advisory Council (NIAC) recommend that the President establish a Task Force on IPv6 to develop a national policy on its adoption. Such a policy should cover the U.S. Federal government and the critical infrastructure industry sectors.

Despite weak market interest in IPv6 at that time, NIAC's catalytic initiative was followed by coordinated government efforts, highlighted by the 2003 DoD and the 2005 Office of Management and Budget (OMB) IPv6 mandates. These efforts led to increased IPv6 interest within the United States and helped reverse its falling behind other nations in terms of understanding and adopting the new protocol.

The goal of this book is to provide a global overview of the strategies that developed around the IPv6 adoption and the perspectives taken on it within various markets. Although several sections briefly cover some technical aspects of the protocol, the objective of the book is to complement the technological viewpoint offered by a growing number of publications in the market with a business perspective. IPv6 adoption drivers and trends are reviewed at international, national, and business levels and some of the practical lessons learned are shared through concrete case studies. It turns out that a smooth and optimal integration of IPv6 depends as much on a good adoption strategy as it depends on understanding the technology.

Goals and Methods

This book intends to provide a business perspective on IPv6 and its adoption, complementing the many technical IPv6 titles available today. It also intends to provide the readers with some of the "whys" and the "whens" applied to IPv6 strategies and some of the "hows" discovered through implementation experience by various organizations, countries, and market segments around the world. If the clamor of IPv6 has reached your desk and you simply want to understand what the big deal is, this book will bring you up to speed.

To that end, the book will present you information that answers the following questions:

  • In a nutshell, what are the real technical benefits of IPv6?
  • What are some of the business and technical opportunities presented by IPv6?

  • What IPv6 adoption strategies have emerged in various markets and throughout the world?

  • What did other organizations do to adopt IPv6?

  • How do I prepare my organization for IPv6?

The book combines market analysis and case study methods to provide the current state of IPv6 adoption. It also provides practical guidelines based on the extensive IPv6 planning and deployment experience of the authors.

Who Should Read This Book?

In the experience of the authors, the big questions of "Why IPv6?" "When IPv6?" and "How IPv6?" are, in various forms and at various levels of intensity, on the minds of all people who are connected with the IT-related aspects of their organizations. These questions still bother the (by now IPv6 savvy) networking specialist as well as the CIOs who start to see IPv6 sneak in among the usual hot topics of VoIP and security. Regardless of their level of familiarity with the protocol, technical and business professionals alike want to understand what drives the IPv6 adoption and to see concrete examples of IPv6 strategies.

This book should be read by IT professionals, by IT department managers, by senior managers, and by executives of all organizations leveraging an IP infrastructure. It should also be of interest to people in academia and to government officials who work on IT-related, government initiatives.

How This Book Is Organized

The structure of the book was developed to start with the larger context of the economic and business importance of IP communications and to gradually focus on the various aspects of the IP upgrade. One chapter is dedicated to debunking some of the common IPv6 technology myths in order to set a realistic baseline for the discussion. The review of perspectives on IPv6 is paired with examples of developed and implemented adoption strategies. The final chapter provides IPv6 integration planning tips gleaned from the lessons learned by organizations that went through the process.

The six chapters of this book cover the following topics:

  • Chapter 1, "The Business and Economic Importance of IP Communications:" This chapter reviews the importance of the Internet in today's economy. It explains why the Internet infrastructure became a strategic asset for nations, enterprises, and service providers. It also reviews the market trends toward an IP convergence that leads to rapid growth of the overall Internet infrastructure and drives the need for an evolution of the Internet protocol.

  • Chapter 2, "IPv4 or IPv6—Myths and Realities:" This chapter discusses the original case for developing IPv6 as presented by the Internet Engineering Task Force (IETF). It provides additional arguments in support of developing a new version of IP based on protocol adoption trends and statistics such as the growing world population. The discussion focuses on some technical aspects of the protocol by reviewing the most popular and notorious IPv4-IPv6 myths that you may encounter regularly in the press and open forums.

  • Chapter 3, "The Economy of an IP Evolution:" This chapter takes a closer look at the constraints presented by an IPv4 infrastructure to national economies and individual businesses. By eliminating these constraints, an IP upgrade opens a set of new opportunities that are less apparent drivers for IPv6 adoption. This chapter presents a more realistic perspective on adoption drivers, a perspective that takes into consideration the foundational nature of the technology considered and departs from the simplistic ROI-based approach.

  • Chapter 4, "IPv6 Adoption Strategies:" This chapter maps some of the adoption drivers analyzed in Chapter 3 to IPv6 adoption strategies that emerged at the beginning of the 21st century. Both "national" and "business" strategies are analyzed independently in a structure that matches that of Chapter 3. Along with the descriptions of strategies, this chapter presents some of the adoption challenges faced by the industry.

  • Chapter 5, "Analysis of Business Cases for IPv6: Case Studies:" This chapter is the core of this book, emphasizing its focus on providing practical information that can be applied in developing IPv6 adoption strategies. The chapter builds on the analysis offered in Chapter 4 by offering concrete, real-life examples of IPv6 strategies developed by various organizations in various markets. The case studies highlight the profile of the organizations in order to help the reader to put the strategies in the proper context and to be able to relate to the environments described. The case studies present the perspective that these organizations have on IPv6 and the drivers they identified for developing the IPv6 strategy. Planning and implementation suggestions and challenges are also discussed.

  • Chapter 6, "Planning Your IPv6 Migration:" As a corollary to the case studies, this final chapter reviews key aspects related to IPv6 planning. It steers away from technology discussions, a topic covered extensively in other books, and focuses on mandatory steps an organization has to take toward a successful and cost-effective deployment of IPv6. There is a lot more to consider in building an IPv6 strategy than the technology itself. This chapter summarizes the experiences gained to date with respect to this process.

Where to Go from Here

Although the industry has reached consensus regarding the inevitability of an IP upgrade, the time to start on that path is largely dependent on the market an organization belongs to, on its long-term vision, and on the national and international environment in which it operates. The timing of an IPv6 adoption is ultimately similar to that of adopting other technologies. It is the result of balancing the benefits and expenses of being an early adopter with the risks of being a late adopter. The important thing in the case of IPv6 is to realize that it is a foundational technology and the benefits or risks of adoption, although potentially significant, might be less apparent. This aspect of IPv6 and its adoption has been made clear by the complex market perception of and approach to the topic.

At the end of this book, if you feel better positioned to confidently define an IPv6 strategy for your organization or you are better informed to understand the reasoning behind IPv6-focused policies enforced within your organization, then this book has achieved its goals. The authors intend to bridge the gap between the technology and the business dimensions of IPv6 to shed some light on a technological evolution with potentially revolutionary business outcomes.

So what's next? A reader with a taste for technology can follow up with books focused on the protocol and its deployment such as Deploying IPv6 Networks by Cisco Press. Most importantly, you can analyze your organization's IPv6 requirements and apply some of the lessons learned here to the development of an IPv6 strategy that ensures its efficient, cost effective, and timely integration in the existing or next generation IP infrastructure.
