IPv6 (Internet Protocol version 6)
What is an IP address?
What is IPv6?
A next-generation version of IP (Internet Protocol), a
basic Internet protocol, in which the number of IP
addresses (numbers to identify terminals) is greatly
increased.

Additional Functionality in Moving from IPv4 to IPv6
1. Dramatic expansion in the address space
–
–
–
IPv4 address space  232 =
4,294,967,296
IPv6 address space  2128 =
340,282,366,920,938,463,463,374,607,431,768,211,456
As the world’s population is about 6 billion, this equals 57,000 x 1 trillion x 1 trillion per person.
If evenly placed across the earth’s land surface, there would be 220 million x 1 trillion per 1cm2
 Networking of non-PC devices
(IP addresses can be allocated to a variety of emerging devices, such as mobile telephones,
home appliances, games and automobiles etc.)
2. Standard Support for Security Functions (IPsec: IP Security)
–
It will become possible to authenticate users and encrypt data when transferring IP packets.
3. Ability to Set IP Addresses Automatically (Plug-and-Play)
–
Includes functionality whereby devices can automatically obtain IP addresses merely by being
connected to the network.
4. Realizes Transmission of Real-time Data such as Voice and Image Data (QoS:
Quality of Service)
–
Enables quality of communication service to be guaranteed by placing low priority on data
communications etc. that can tolerate delay and high priority on voice and image data that cannot
tolerate delay.

IPv6 in Governmental Policy - Japan
General Policy Speech by then Prime Minister Yoshiro Mori
to the 150th Session of the Diet (September 21, 2000)
Expressed the determination to contribute to the development of the Internet
by participating in tackling global Internet issues with such tools as IPv6.
e-Japan Strategy (January 22, 2001)
Promote the shift to the Internet networks equipped with IPv6 that provides
enough address space and stricter protection of privacy and network security,
anticipating that various Internet access devices and digital home appliances
will become popular and constantly connected to the Internet.
This approach is also presented in “e-Japan Priority Policy Program”
(March 2001) and other policy initiatives thereafter.
Roadmap showing a path to IPv6
from:
Second Interim Report of the Telecommunications
Council on the “Internet Policy Direction in the 21st
Century”(August 7, 2002)
Current status
- Basic R&D was completed.
- Taking a look at international R&D trends, many
countries have geared up.
- The current IPv6 is still at an initial stage for
practical operations before the full-scale
introduction phase. It bears a similarity to the
status of IPv4 a decade ago.
- In the years ahead, as the existing IPv4-based
infrastructure become compatible with IPv6, IPv6
will be deployed at an introductory stage for fields
newly introducing the Internet.
Roadmap showing a path toward transition
- 2002 - approximately 2003: IPv6 initial phase.
IPv6-ready products are to be increased.
- Approximately 2004 - approximately 2006: IPv6
full-scale introduction phase. The replacement of
old systems with IPv6-ready systems will be
implemented and IPv6 will be deployed at an
introductory stage for fields newly introducing the
Internet.
- 2007 onwards: further development phase of IPv6.
Internet infrastructures will become IPv6-ready in
almost all cases, thus practical use of the Internet
enjoying the advantages of IPv6 will be diffused.
- For facilitating the transition of IPv4 to IPv6, based
upon this Roadmap, it is essential for each player
to act with a common understanding in coping with
challenges below.

Replacement of old systems with IPv6-ready systems
Increase in the number of IPv6-ready products
Challenges to be tackled by each player (1)
- Manufacturers, etc.: It is critical to make their products
(network equipment and software) for IPv6 at an early
stage. Then, further enhancement of their products in
terms of stability, performance and operability is
required.
- ISPs: It is vital to provide IPv6 access service at an
early stage. To this end, establishment of know-how
on IPv6-based network operations and fostering of
human resources are needed.
- Homes: While an IPv6-ready outlook will take hold
among residential consumers along with replacement
of PCs, it will be matters of importance for
manufacturers and ISPs to prepare such solutions as
autoconfiguration functions for residential consumers
who do not have the necessary expertise.
Challenges to be tackled by each player (2)
- Corporate users, etc.: When updating computer
systems, there is a need to introduce IPv6-ready
systems considering the lifetime thereof. For that
purpose, first of all, system divisions and system
integrators of each corporate user are required to
clearly understand IPv6.
- New fields: Fields in which the Internet will be
introduced anew, it is essential to employ IPv6ready products at an introductory stage.
- Government: Its status as an Internet user is the
same as corporate users. It is indispensable for the
government as a facilitator, who prepare an
environment suitable for Internet infrastructures, to
take necessary measures for implementing
verification experiments on the transitional model.

Promotion of the transition to IPv6 Internet
Aiming at becoming the most advanced IT nation in the world status, we conduct demonstration
experiments to realize a smooth transition of the whole Internet infrastructure from IPv4 to IPv6. Through
this experiments, we seek solutions to network operational problems, while developing transition models.
○ Select a model area which consists of a local government, enterprises and home users, etc. and conduct demonstration experiments
2003 targeting a transition of the whole Internet infrastructure from IPv4 to IPv6.
from
○ While seeking solutions to network operational problem, develop the optimal model for a smooth transition to IPv6, without
adversely affecting IPv4 based services.
○ In order to promote the transition to IPv6 world wide, we will distribute IPv6 transition know-how to the rest of the world by
releasing the results of the demonstration experiments, standardizing activities in international organizations, etc.

International trends for IPv6
Transition to IPv6 has recently increased importance worldwide. The European and AsiaPacific regions in particular are actively engaged in formulating national strategies and
implementing various projects.
Europe
17 R&D until 2004. Expenditure by the Commission
beyond Euro64mil.
"eEurope 2002"(March 2000) expressed intention to move
toward full conversion to IPv6. "
EU IPv6 Task Force," launched April 2001, released
reports on the IPv6 2005 Roadmap Recommendations in
January 2002.
"eEurope 2005" ( May 2002) proclaims active use of IPv6.
USA
"ESnet" (research institute under the US
Department of Energy) ---- operation projects
"DREN" (experimental network of DoD)
---- v6 procurement equipment
Asia
[Korea]
The Government leads various IPv6 projects.
In February 2001 the Government an announced official
statement to give a boost to the introduction of IPv6.
46.8 billion Won government budget is earmarked until
2003.
[China]
I view of the increase in the number of the Internet
users, the Government is engaged in introduction of
IPv6 as national strategy.
[Taiwan]
The Governments task force "National Information &
Communication Initiative"plays a central role in
promoting the transition to IPv6.
"IP v6 Diffusion Plan"(October 2001)
"E-Taiwan Plan" (May 2002)
Conclusion
- Transition toward IPv6 is a "must."
- Sooner or later it will be realised. But transition
without affecting the existing Internet requires
more prudence.
- Education and training of engineers is vital.
- Those parties commercially involved in the Internet
should act bearing IPv6 in mind, to become IPv6ready.
- Governments should act as both users/advocates.
- Front runners including Japan should present their
transitional models to other countries, and further
contribute to worldwide deployment of IPv6.
