If you don't have too much IPv4 addresses, what is your solution?

是不是 中國電信（共慘黨鐵蹄下的奴才）引蛇出洞的陰謀呢

Many countries, including China, have asked for transition from IPv4 to IPv6. Technically, all new network equipments are compatible with IPv6. But WHO blocks this transition?

Remember the Millennium bug? I think it is more serious than ip address transition.

Most ISPs have redundant system, which could ease the transition a lot. However, many ISPs just follow the rule: don't break it as long as it works.

From wiki:

As of September 2013, about 4% of domain names and 16.2% of the networks on the internet have IPv6 protocol support.

I consider it as seamless(無縫).
