Title :
From IPv4 to IPv6: Challenges and Opportunities
Provide a concise formulation for the proposed workshop theme including its importance and relevance to the IGF.

Internet Protocol (IP) is the core address resource of the Internet, but the current version 4 (v4) has finite numbers of remaining pools and if the current consumption rate continues, it is estimated to reach its exhaustion sometime in three to five years from now according to various experts’ estimates. The only practical and long-term solution to this challenge is to use IPv6 addresses.

Therefore, we must make sure that the transition to IPv6 be as smooth and stable as possible for all the global Internet users. In reality, the current v4-based networks and services will not disappear at all, but they will remain functional, plus we need to add new v6-based networks and services on top of existing v4 networks and make v4-based services and v-6 based services interoperable.

This is a great challenge. It will have many implications for different players in the Internet ecosystem including individual users, SMEs and large corporate users, non-commercial users, ISPs, vendors, governments, etc. A smooth and predictable transition for all users will contribute to the continued stability of the Internet.

Yet, more awareness of the importance of transitioning to IPv6 is needed: for example, among businesses - how moving to IPv6 will ensure continued business certainty; and among governments - particularly in terms of ensuring the continuity of governments services, etc. There are lots of works to be done in the operational areas, too. 

Much technical work is to be done by research and development community in academia and industry. We need to develop technologies for IPv6 network and applications as well as fir making IPv4-v6 “coexistence” a feasible reality.

Developing the technologies is not the end-goal, but we must implement these into the new and existing operational networks. Certain equipment must be upgraded or replaced to make them IPv6 ready or IPv4-v6 “dual-stack”. Much software must also be modified or added to function smoothly in the new network architecture and environment. New rules and policies may also be introduced and implemented. These require good amount or resources, both financial and human.

Much awareness campaigns are thus needed in the policy, business and consumer education areas. Recent report of Japanese Government “Study Group on Internet’s smooth transition to IPv6” summarized their comprehensive analysis of the issue and possible Action Plan by different stakeholders is one good example to be shared with others. This report argues that considerable impact may happen to end-users  unless appropriate and timely measure are taken.

At this workshop, we would like to highlight how the concerned parties in charge are addressing these challenges, and what sort of measures have been already taken, or under discussion and going to be implemented, for both IPv4 address exhaustion and
preparing for the IPv6 address transition.

We will also examine the public policy implications, possible roles and responsibilities of governments, the Private Sector and the Civil Society.  The session will also focus on development issues, including how to ensure a smooth transition to IPv6 among the stakeholders in developing parts of the globe.

Provide the names and affiliations of the panellists you are planning to invite. Describe the main actors in the field and whether you have you approached them about their willingness to participate in proposed workshop.

  • NRO (Number Resource Organization) - Technical Community
  • Internet Society (ISOC) - Technical Community
  • Internet Association Japan (IA Japan) - Private Sector

  • Google – Private Sector
Does the proposed workshop provide different perspectives on the issues under discussion?

YES. We believe that this workshop will provide perspectives focusing on the pragmatic and operational issues in addition to the address allocation, across technical, business and public policy sectors in global context. So far there has been no such event taken place in the international community we are aware of.


Please explain how the workshop will address issues relating to Internet governance and describe how the workshop conforms with the Tunis Agenda in terms of substance and the mandate of the IGF.

We believe this workshop will conform to the Tunis Agenda with the following paragraphs:


45. We underline the importance of the security, continuity and stability of the Internet, and the need to protect the Internet and other ICT networks from threats and vulnerabilities.

49. We reaffirm our commitment to turning the digital divide into digital opportunity, and we commit to ensuring harmonious and equitable development for all.

55. We recognize that the existing arrangements for Internet governance have worked effectively to make the Internet the highly robust, dynamic and geographically diverse medium that it is today, with the private sector taking the lead in day-to-day operations, and with innovation and value creation at the edges.

70. Using relevant international organisations, such cooperation should include the development of globally-applicable principles on public policy issues associated with the coordination and management of critical Internet resources.

For the IGF mandate:

We believe this workshop will conform to the mandates of the IGF in para. 72, because it will fit with the following points:

1. Discuss public policy issues related to key elements of Internet Governance in order to foster the sustainability, robustness, security, stability and development of the Internet (72-a)

2. Facilitate discourse between bodies dealing with different cross-cutting international public policies regarding the Internet and discuss issues that do not fall within the scope of any existing body; (72-b)

3. Advise all stakeholders in proposing ways and means to accelerate the availability and affordability of the Internet in the developing world; (72-e)

4. Identify emerging issues, bring them to the attention of the relevant bodies and the general public, and, where appropriate, make recommendations; (72-d)

5. Discuss, inter alia, issues relating to critical Internet resources; (72-j)

List similar events you and/or any other IGF workshops you have organized in the past.

We have organized the Workshop on the same subject at the IGF in Rio de Janeiro in 2007.

Were you part of organizing a workshop last year? Which one? Did you submit a workshop report?

YES – IPv4-v6 Workshop

We have submitted the draft transcriptions and presentations.
