Workshop on IPv6
Geneva, Switzerland 4 — 5 September 2008
With the massive deployment of Internet-related resources
worldwide and the integration of IP-enabled consumer devices connected
directly to the network, the issue of the depletion of IPv4 addresses is
becoming pertinent. Indeed, there is wide recognition of the need for
better awareness of the availability of IPv4 addresses and the
deployment of IPv6.
Despite the use of network address translation (NAT) as a strategy for
reducing the use of public IPv4 addresses, several experts forecast
depletion in the next few years. In addition to other features, IPv6
with its 128 bit address space is aimed at addressing the current
shortage of public IPv4 addresses. However the transition from IPv4 to
IPv6 is going at a rather slow rate, with both versions being used in
parallel. Many informed observers attribute this to market forces and
other economic considerations.
There is growing interest in IPv6 especially among the organizations
involved in its management. ITU is organizing this workshop in order to
foster dialogue and international cooperation on IPv6 related issues.
The workshop will provide a platform for dialogue where key players in the
field, including all ITU sectors, as well as other interested entities will
be able to discuss and address international public policy issues on the
migration to IPv6, as well as the economic aspects related to IP address
Session topics will include:
The workshop is designed to stimulate discussion and interaction with the
audience, rather than a string of presentations and speeches provided by
panelists and speakers.
Participation from developing countries is strongly encouraged.
Relevant outputs from the workshop will be further studied as appropriate
The workshop will address some of the key issues, in particular the following questions raised in contributions to ITU-T Study Group 3:
Information and Documentation
Other questions will be addressed as appropriate.
- What economic or tariff incentives could be put in place in order to make
sure that IPv4 addresses allocated by the RIRs are used efficiently, when they
are not any longer used; that they are given back to the global community; and
are not hoarded?
- What are the direct and indirect costs related to fraud, spam, etc. that is
facilitated because of NATing and other techniques currently used to conserve
IPv4 addresses, because those techniques make it more difficult to trace the
origin of particular packets or E-Mail messages?
- What are the costs of migration to IPv6, in particular for developing
countries, for example for:
- Capacity building
- New equipment (routers, etc.)
- Configuration (e.g. maintenance of dual-stacks, tunnelling, etc.)
- What, if any, are the network externalities involved in the migration from IPv4 to IPv6?
- What would be the economic or tariff effects if a secondary market is created for IPv4 addresses (that is, allowing current holders of IPv4 addresses to sell them to other organizations)?
- What would be the impact — in particular for developing countries, taking
into account that tariffs should be cost-oriented — of the growing scarcity of
IPv4 addresses and of a), b) and c) above on:
- Settlement rates for voice traffic that is carried over IP networks at
the wholesale (backbone) level
- International Internet connectivity (IIC) (ITU-T Recommendation D.50)
- Termination rates for IP telephony
- Next generation networks (NGN)
