我们中国发展互联网较晚，西方已经把一些IP地址分配地差不多了，留给我们的不多，而不够用。因此我们积极推IPv6，而西方却不太感兴趣。IP地址不够用，于是因祸得福，我们便开发了动态IP的技术，即你需要联网时，从IP地址池中选一个分配给你用。当不用网时收回IP到池中，以供其它人用。即IP地址是不固定的。因此天然给我们大陆用户多了个IP层的隐私保护。不必太过于担心IP地址泄露。而西方每设备绑定固定的IP，因此才更担心IP泄露。🐇ᥬ[🐕]᭄🌿

That's an interesting observation about the evolution of IP addresses and how different regions have approached the issue of IP address scarcity. It's true that the development of IPv6 has helped to alleviate the pressure on available IP address space, and the use of dynamic IP addresses can provide some level of privacy protection for users by making it difficult to link specific IP addresses to particular individuals or devices. However, it's worth noting that IP addresses are not the only factor involved in online privacy and security, and there are many other ways that online activities can be tracked or monitored. It's important for users to take steps to protect their privacy and security online, such as using encryption, strong passwords, and trusted privacy tools, regardless of the type of IP address they are assigned.
另外ipv6的利用率接近没有，全世界绝大部分人都是Ipv4模式，没什么差别
忘了还有Mac Address + 路由器上存的设备名，要变这个太难了，比翻墙难太多了。
