I don't know of any big news sites that are blocked in China.
Neither do I, although I'm not actually interested enough in the subject to bother researching it. If you're in china, though, are you sure blocked sites don't exist? They could be just be blocked, you know.
Who the hell needs 13 Gazillion addresses on their LAN? On the internet sure, ok....who the fuck going to connect a Windows box to the internet without NAT/Firewall?
Network address translation came into use because you had limited supply of IP addresses, pigeonhole problem basically. With IPv6 that's not needed, because surely 3.4×10^38 addresses should be enough for anyone. You'll just need a firewall to reject requests from outside your own assigned block.
