The Internet has been using IPv4 since the 1970s. The biggest difference between IPv4 and IPv6 is the address space: IPv4 has a 32-bit address space; IPv6 has a 128-bit address space — a huge increase. The number of unallocated IPv4 addresses is rapidly shrinking. IPv6’s 128 bit address space will supposedly allow a unique IP address to be assigned to every atom on earth; it’s unlikely that we’ll run out of IPv6 addresses anytime soon.
China is taking the opportunity of hosting the 2008 Olympics Games in Beijing to roll out IPv6, which some have labeled as "leapfrogging" the rest of the world. It plans to have thousands of cameras and sensors, each with a unique IPv6 address, monitoring Olympic activities. I guess that China looks upon this as a 21st Century technological great leap forward.
In western Europe and the United States, where it was once feared that unallocated IPv4 addresses would disappear before 2000, the proliferation of routers with network address translation (NAT) has relieved the pressure on IPv4 addresses.
The big question is, When will China stop censoring Internet use?
