    为什么关心 AS

因特网上的一个 IP 必定属于某个 AS，也就是一个自治系统。一般一个 AS 里的 IP 具有共性，比如网络质量较高或者较差，欺诈风险较高或者较低。
在使用 mtr 或者 traceroute 查看路由时，通过确认中间路由节点 IP 的 AS，可以确认路由质量。
举例说明，对于常见的 CN2 线路，通过 mtr 看到有经过 59.43.138.70，使用 whois 命令查看 IP 信息如下
~$ whois 59.43.138.70
route:          59.43.0.0/16
descr:          Chinatelecom Next Carrying Network backbone
origin:         AS4809

                IPv6 完全随机化连接
              
          
    使用整段 IPv6 以避免被墙的设置方案：
服务端

假设我们拥有 2602:feda:db8::/48 这段 IPv6 地址，且该段地址被静态路由至我们的服务器。
首先配置防火墙，详略。
将整段 IPv6 地址配置至服务器：

    Writeup

首先运行一下 python ether_v2.py，这个程序需要输一串东西，而输各种东西都只能看到一个 You are too vegetable please try again!。试图劫持各种函数，也发现对获取程序逻辑没有太大帮助，那么还是老老实实看字节码吧。
试着反编译了一下，但是也出错。把 dis 模块的代码拷过来调试，发现程序一开始就是个大跳转，而很多不会被执行的地方也有很多非法指令。可以按照跳转的顺序输出字节码，就能得到比较容易分析的结果了。
