see below for china ranges I believe, ipv4 and ipv6
You may believe... but are you *sure*? (Over the years, we've seen *lots* of "block China" lists that accidentally block chunks allocated to Taiwan or Australia or other Pacific Rim destinations). And remember - asking the NIC doesn't help, because there are almost certainly blocks allocated that the registration points to Korea or someplace, but the provider routes a sub-block to China. And let's not even get started on blocks allocated by ARIN or RIPE.... (Yes, it *was* a trick question :)
