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 ?

A Large-Scale IPv4 Network BuiltConcerned with the benefits of IPv6 IPv4 still can manage to work How to use existing IPv4 equips Cost for Transition Maturity of IPv6
Hence and egg Problem No operational network to support app No killer app to promote Network deployment

Future
Developing Native IPv6 Network Parallel 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
