GFW DNS 污染 IP 列表

来源：http://blog.lrfz.com/?p=535

GFW 最近半年愈发猖獗。一个直观的个人的体验是：以前用 FoxyProxy 也就是建个翻墙白名单；现在已经是全天开 proxy 上了，在考虑啥时候建个不翻墙的白名单。当然，Tor 也被干扰了，速度慢，而且要经常换 Bridge 。后来还是花钱和朋友合租了 VPS，用上了 SSH Tunnel。

关于翻墙这种行为，我要强调的是：这是个人在基本的言论和通讯权力被侵害时的被动的生存行为；墙和墙的所有者是没有法理基础的；建设、维护和拥有墙都是侵害人权的罪恶和违法行为；这种罪恶不因民众的翻墙能力增长而减小。

以下是正题：最近我在给自己的 Android 手机用 VPN 翻墙，路由问题已经有解，DNS 似乎更容易。但由于 Android 系统的一些问题，DNS over VPN 在某些情况下不稳定，所以 hosts 文件是一个有必要的补充手段。关于抗 GFW 的 hosts 的文章不少，但大多只给了 Twitter, Youtube 等大网站的 DNS 记录；Hosts File Patch提供了 Windows 下的若干 hosts 的 hosts patch。 在"深入理解GFW：DNS污染"一文中，提到了 GFW 在 DNS 污染中使用的 8 个 IP:

  • 4.36.66.178
  • 203.161.230.171
  • 211.94.66.147
  • 202.181.7.85
  • 202.106.1.2
  • 209.145.54.50
  • 216.234.179.13
  • 64.33.88.161

而我的兴趣是：

  1. 调查更多的 GFW 使用的 DNS 污染 IP
  2. 建立和维护一份覆盖更广泛的 Anti GFW Hosts 文件

针对上述第一个问题，我使用了一些简单的 Web 服务，获得了一个较长的 Faked IP list:

  • 4.36.66.178
  • 8.7.198.45
  • 37.61.54.158
  • 46.82.174.68
  • 59.24.3.173
  • 64.33.88.161
  • 64.33.99.47
  • 64.66.163.251
  • 65.104.202.252
  • 65.160.219.113
  • 66.45.252.237
  • 72.14.205.104
  • 72.14.205.99
  • 78.16.49.15
  • 93.46.8.89
  • 128.121.126.139
  • 159.106.121.75
  • 169.132.13.103
  • 192.67.198.6

对这些 IP 作 Whois 查询见附件 whois 。

GFW 很可能还使用了其他的 IP 进行 DNS 污染，而在未来还可能使用其他的 IP 。本文显示，GFW 在 DNS 污染中使用的 IP 是可以被跟踪的，并可以进一步对于被污染 domain name 进行跟踪，并用于维护一个 hosts 文件来规避 GFW DNS 污染。在以后的一段时间，我将进一步分析被污染的 domain name 并试图建立和维护这个 hosts 文件。
