Yeah, I was shocked to discover that as well. They implement the NAT444 model, so I do get a public IPv6 /60 subnet for all the “internet of things” in the house. But they had to do it wrong in some way, so it’s dynamically allocated and keeps changing. (I tried to ask for static, reply was I need to pay for static IPv4 to get static IPv6 as well – stupid, but I did not have the patience to argue.)

As for Tor, it has many different ways to connect, that are designed to circumvent many different ways to block users, and both are constantly evolving. I find it hard to believe that a bus company is ahead of the Chinese government on this front. 🙂
