At the recent meeting in New Delhi the ICANN At-Large Advisory Committee (ALAC) formed a policy working group to focus on IPv6 migration issues.
In ALAC’s view, IPv4 will never be completely obsolete thus it is also important to work out compatibility issues between the two systems.
A mailing list has been established. All interested parties are invited to subscribe.
At the Delhi meeting the Japanese government made an extensive presentation on the topic.
