Internet in China
The number of Internet netizens in Chinahas reached 0.384 billion, occupying 28.9%of whole population.
The number of mobile netizens in China hasreached 0.233 billion, occupying 60.8% ofwhole netizens.
The number of IPv4 addresses increases
dramatically each year.
IPv4 Addresses: 232,446,464, rise 28.2% than2008
Domain name: 16,820,000, 80% of which are .cnBackbone: 2.5-10G
Exchange Points: over 100G (Beijing, Shanghai,Shenzhen)
International Links: 866,367 Mbps, rise 35.3%than 2008
IPv6 Addresses: 63 /32

Why we need IPv6
Population in China is more than 1.3billion Regardless on other usages, 1 IP address per person,
we need at least 77 /8 IPv4 address
According to ICANN in March 2010, only 22 /8 left in
global pool, no sufficient IPv4 address available now
The IPv4 address will be exhausted in 2012
The number of mobile phone subscribers in China is
more than 756 million by January, 2010
If all connected to Internet, more than 29 /8 IPv4
addresses needed
3G licenses were released in January 2009 and China
carriers deploy their 3G/BWA Services

Conclusion
Exponential growth in Internet and mobile users in China pushing the boundaries
of IPv4 and augmenting IPv6 adoption.
As the world largest Internet user country, China wants to leverage IPv6 Internet
technology to build intelligent infrastructures.
Government re-organization will speed up the industrialization upgrade process.
2008 Olympics has dramatically accelerated the maturity of IPv6 application and
service, China will become the one of the engines and flagships to new Internet
economy.
CERNET2 and vast IPv6 expertise, promotes the early adoption of IPv6 enabled
applications and technology.
