---------[ 0x1 - 前言 ]

一两年前,访问网站的时候经常被重定位到北京宽带智能纠错网站去，比较烦人。
后来一段时间好象也没有了，也就没有注意了。这几天，访问网站的时候又经常出现
一些奇怪的现象。初步判断网络有点问题，当然我能确保我的系统是干净的。

使用环境 winxp sp2 firefox，北京网通ADSL拨号上网，使用DHCP自动分配IP和获得DNS，
不使用IE是因为IE自身也内嵌了3721查询，正确的说是内嵌了auto.search.msn.com.

关键字：DNS查询，HTTP协议，WHOIS 查询，DNS轮循

---------[ 0x2 - 一些怪现象 ]

这里就不重述DNS是如何工作的，以及DNS在整个互联网中的重要性。

---------[ 0x2.1 - ping一些不存在的域名 ]

先来看看一些现象：

为什么会这样，明名胡乱打的一个域名为什么会返回一系列IP地址呢，是偶然
还是巧合?

dns服务器返回的一些ip地址

很显然dns服务器告诉我们的就是：fuck123445452.com的ip地址为202.108.251.213

---------[ 0x3 - 浏览器浏览不存在域名被重定位 ]

---------[ 0x3.1 - 现象 ]

  再来看看http协议上的问题，我们用firefox敲了一个网址进去
www.chinatesttesttest.com (特意查了下，这个域名是还没有被人注册的) ,
结果返回回来的是

是不是觉得奇怪呢，是的，不奇怪才怪了呢

---------[ 0x3.2 - 抓包分析 ]

抓包分析吧

firefox的动作

★ 第一步
  查询www.chinatesttesttest.com的ip地址，如上一样dns服务器返回
  202.108.251.215

★ 第二步
  2.1 向202.108.251.215发送GET / HTTP/1.1/r/n请求。
  2.2 202.108.251.215返回数据

ok这里出现了bobodogs.com和jcdh.cn这两个网站。
看看这两个网站分别是什么
jcdh.cn是北京宽带网网站。(后补：是乍看是)
bobodogs.com是博博狗。
他们俩什么关系？？

---------[ 0x6 - 一次被引导到3721网站的过程 ]

  按照上面的分析，现在只要访问一个没有注册的域名的话，会经过一系列的过程后看
到一个网站不可访问的页面。也就是下面这个

===============================================================
无法显示网页
您正在查找的页当前不可用。网站可能遇到支持问题，或者您需要调整您的浏览器

但是有几次这样的一个过程居然被引导到了3721的查询网站上去了。
我们再来看看这个过程的细节吧。

  ★ 第一步进行dns查询 testtest3.localdomain

==============================================================

  一个还没注册的域名，这次返回的IP是61.51.18.112.
  经过whois查询，这个IP地址信息如下：
==============================================================
inetnum:      61.51.16.0 - 61.51.31.255

==============================================================
Hypertext Transfer Protocol

    </Script>

==============================================================
    直接重新导向本网站的/URLAsk


  ★ 第三步访问61.51.18.112 的/URLAsk 返回的数据为
==============================================================

==============================================================
    又重新导向auto.search.msn.com，auto.search.msn.com会使用3721的东西来搜索，返回给用户看到的
就是yahoo的3721网站搜索。到此，通过dns的引导，网站的配合，最终引导到yahoo的3721搜索网站。

我们看到
  最上面的title是显示的北京宽带网－纠错导航，
  左上角使用的北京-宽带网-BNN的logo,还有“温馨提示：您输入的域名或网址无法访问！
      可能是输入错误，或是网站访问超时”，
  左下角是一个error.html页面， http://www.jcdh.cn/error.html ，显示
      无法显示网页，模拟的是 Internet Explorer 找不到服务器或 DNS 错误的错误。
      (我可是用的是firefox啊)
  右边是连接到www.bobodogs.com的内容。

---------[ 0x8.1 - 影响用户范围 ]

  从51.la的统计上来看，影响的是北京网通的ADSL拨号用户

---------[ 0x8.2 - 解决办法 ]

  假如你比较厌烦这个东西的话，不要设置自动获得DNS服务器地址，自己手动添写非网通的DNS服务器。
  比如北京电信的 202.96.199.133  202.96.0.133  202.106.0.20  202.106.148.1  202.97.16.195
