---------[ 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

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。

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

202.108.251.206
202.108.251.207

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
===============================================================
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
设置。

请尝试以下操作:

    * ·单击 refresh.gif (82 字节) 刷新按钮,或稍后重试。
    * ·如果您已经在地址栏中输入该网页的地址, 请确认其拼

==============================================================
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??
