In Mainland China, in many regions, the discriminatory firewall (GFW? Data discrimination by operators for commercial interests?) imposes almost no censorship on IPv6 communication.
For example, in Henan province using China Unicom broadband, obfs4 bridges under IPv4 are almost always blocked within six hours. However, IPv6 was not blocked until a month later when I couldn’t pay the server bill and shut down the server.
Based on this experience, I hope Tor can make more use of IPv6 networks (preferably achieving ‘IPv6 Only’).
在中国大陆（Mainland China）有很多地区的歧视性防火墙（GFW？运营商出于商业利益的数据歧视？）对IPV6通信几乎是没有审查的。
例如，在河南省使用中国联通宽带，IPV4下的obfs4网桥几乎在六小时以内就会被封锁，但IPV6直到一个月后我支付不了服务器账单关闭服务器，都未被封锁。
基于这项经验，我希望Tor可以更多的使用IPV6（最好可以实现“IPV6 Only”）网络。
