Different Voice

How many IPv4 addresses can China get？

Will IPv4 NAT work for China?

Should China implement IPv6?

Who pay for IPv6 transition?

Will China benefit from new features of IPv6 ?

What are the killer applications of IPv6 ？

Future

Developing Native IPv6 NetworkParallel Develop with IPv4 Internet

Merge Transparently with IPv4 on service and application level

Maybe First Success in Some Special Area

Success Depends on the Speed of Commercialization
