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 ？

China Netcom

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
