The recent Federal Summit for IPv6 was both a successful event and established another milestone in the history of IPv6, as the time and place when major government agencies came out with strong affirmations as to how and why the federal departments are transitioning to IPv6. The purpose of this Summit was to provide a smaller, more focused event in support of the US Federal Government and its transition to the IPv6 standard, but there was still very strong attendance, with over 400 participants and dozens of speakers and panelists. VIP presenters included IT executive officers of Federal departments, representatives of the Department of Defense, the Presidents of the Federation of American Scientists and the IEEE-US (the largest professional organization in the US), and representatives of the emergency response community and major Internet organizations such as OPEN and ARIN.

Hot panels on cybersecurity, emergency response to Katrina-type events, network configuration and DoD Transition lessons learned brought both audience involvement and endless questions, a sure sign of interest and intent. Several of these topics sparked a lot of interest from the national Press, which learned that progress with IPv6 can – quite literally – be a matter of life and death. The initial report on the First Internet City in America brought a much needed topic to the forefront: how and where can we see actual v6 applications – and how can providers make a profit on them?

The Tutorial Day on 17 May was SRO, as participants got insights from experts in two separate tracks, one on Transition Management, and one on Advanced Security and Network Technology. Finally, our wonderful corporate supporters, including Grand Sponsors Juniper Networks and Spirent Federal Systems, Gold Sponsors Lucent, NTT, Microsoft, Foundry Networks, Global Crossing and InfoWeapons, and Silver Sponsors Intelliden, Software Engineering Services, Digital Presence, Fortinet, Innofone.com, v6 Transition and Infuse Creative, did their best to enable attendees to get both an experience of the latest and greatest in various products and services and to share experience-based insights on best practices and how to overcome the challenges of transitioning to IPv6-capable networks.

We thank all of our great speakers, panelists, sponsors and attendees for making the Federal Summit for IPv6 a well-attended, content-rich and fruitful event.

In this month’s 6Sense we have several articles meant to inform and pique your interest. Dr. Henry Kelly, the President of the Federation of American Scientists, writes about the status and needs of the US educational system, and how advanced technology could make a huge difference to both learning and competitiveness in our Nation. The implications for IPv6 – in enabling collaborative networking, in providing secure end-to-end transactions and “trusted networks,” and in supporting the creation of immersive 2D and 3D multimedia environments – are obvious. Since education may well become one of the killer apps for IPv6, we laud the participation of this community in our Summits and 6Sense, and hope to hear much more from government and academic training experts in the future.

John Lee, the SVP of Business Development for Internet Associates, gives us his insights into how to renumber a large-scale IP network, and how an IP Address Life Cycle Management Solution can reduce the time and effort for this essential aspect of a v6 transition implementation. Dale Geesey, the Vice President of v6 Transition, writes about one of the hotly debated topics of our community – the depletion of IPv4 addresses – and suggests a market-based approach to allocating the remaining address space. One interesting outcome of such a strategy might be the genesis of a simple partial ROI calculation for companies: “Should we buy a block of v4 addresses at price X, or transition to v6 at price Y?” Lawrence Hughes, the CTO of InfoWeapons, clues us in on the real history of the Internet address shell game in “The Dirty Little Secrets of ISPs,” drawing on both deep knowledge of the subject and his remarkable talent for making complex topics comprehensible even to non-techies.

We hope that you enjoy the articles and insights, and welcome your feedback, both in terms of submitting articles and your comments on how we can serve our IPv6 community ever better and more comprehensively.

The Dirty Little Secrets of ISPs

One of the main benefits of moving to IPv6 is the restoration of full end-to-end connectivity, Internet-wide. In the original Internet, all IP addresses were "static externally routable" addresses. Any node on the Internet could connect directly to any other node on the Internet. All was right with the world. Then we started running out of addresses, about 10 years ago! I'm going let you in on some of the dirty little secrets of Internet Service Providers regarding how they have tried to cope with this reality.

Let's look in more detail at the phrase "static externally routable addresses."

Private Addresses and NAT
The "externally routable" part of this phrase refers to the use of "private non-routable" addresses, as described in RFC 1918 ("Address Allocation for Private Internets") released February 1996 – I told you this problem has been around for ten years!). As we started running out of IPv4 addresses, the authors of this RFC came up with the idea of setting aside a few special address ranges (, and that could be used in anyone's "internal network," much like three- or four-digit "extension numbers" in an office phone system. Say my office phone is "extension 1234." You can't simply call that number from anywhere in the US – you must call one of the company's "real" phone numbers, then either have a receptionist or machine further connect you to my extension ("if you know the person's extension, dial it now").



Can a Market-Based IP Allocation Approach Save IPv4?

How long will IPv4 addresses be available? That has been a question asked many times over the past decade and a half. In the early 1990s, projections within the Internet Engineering Task Force (IETF) showed the imminent depletions of the IPv4 address space under the current methods of use and allocation. In response, a two-pronged approach was employed to mitigate the pending crisis. The first part of the approach was to delay the complete depletion of the IPv4 address space. This was accomplished through a combination of techniques, including the use of more rigorous address allocation policies and with Network Address Translation (NAT). While the delay in total IP address depletion was successful, it was neither intended to be nor could be the final solution. The second part of the approach was to develop a replacement for IPv4 that would provide enough address space to support Internet growth for the foreseeable future. The IETF initiated a working group called IP Next Generation (IPng) that eventually led to the development and standardization of IPv6 in the mid-1990s.

Although the delay of the IP address depletion has been successful, over a decade later the industry is once again debating when IPv4 address depletion will occur with estimates that the Regional Internet Registries (RIRs) will run out of IPv4 address space between 2008 and 2013. That is unless another method is found to once again extend the life of the IPv4 address space. One approach that has been discussed in the past and recently reintroduced by a major IT research and advisory firm is the idea of allowing market-based approach to IP address allocation.



IPv6 and the Future of Learning

There's no hiding the challenges facing education systems in the US. The definition of a "basic education" keeps expanding, the people needing educational services are increasingly diverse, and funds are increasingly tight. Innovation is essential to meet these challenges and modern information technologies, powered by IPv6, have a key role to play. These technologies make it possible to provide more people expertise in more areas at lower cost – and do it in a way that is much more personalized, engaging and compatible with the frantic lifestyles of modern Americans. These new learning technologies will not emerge under "business as usual." New public and private institutions must be invented to exploit them.

Modern international research networks feed on each other, creating powerful positive feedback that continuously expands the scope and power of what we know. Modern engineering converts this knowledge into devices and systems of staggering complexity. But, this new knowledge and these new devices and systems are useful only if the knowledge can be assimilated and properly applied to address relevant needs.

This paper describes the author's experiences related to the architectural changes and renumbering of a multi-national fiber optic and IP based network that spanned three continents. While the renumbering was IPv4 to IPv4, the techniques and experience are directly applicable to IPv4 to IPv6 transition planning, implementation and operation. The primary difference in today's environment is due to the development and use of an IP Address Life Cycle Management solution and how it reduces the engineering planning, time and effort. It also produces graphical views, better records and relational information for continued operational management of the network.

With little operational experience in large IPv6 networks, we rely on relevant experience with existing technologies that give us a window into the issues at hand such as Integrated Services Digital Networks (ISDN) and large multi-national IPv4 networks. The transition to ISDN was one of islands of (digital) ISDN that were originally interconnected by analog transmission services. BRIs are used to connect Customer Premise Equipment (CPE) to the network and PRI's are used to interconnect Wide Area Networks (WAN) and for network to network connections. For ISDN to be fully deployed it requires digital switches to replace the 1AESS, fully digital long haul facilities for PRI's and Signal System #7 for signal control in a separate control plan from voice or data.
