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.
