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?

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 ]

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) ,

★ 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。

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

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

Data length: 4
Addr: 61.51.18.112
==============================================================
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

==============================================================
★ 第二步 访问61.51.18.112这个网站 返回的数据为
==============================================================
Hypertext Transfer Protocol
HTTP/1.1 200 OK\r\n
Set-Cookie: JSESSIONID=8B31638C6757CB1337F65F6E21B6107E; Path=/\r\n

document.write("<meta HTTP-EQUIV=\"Content-Type\" Content=\"text-html; charset=gb2312\">");
document.write("<head>");
document.write("<META HTTP-EQUIV=\"refresh\" content=\"0.1;URL=/URLAsk\">")
document.write("<title>No Page Found</title></head>");
//document.write("<FrameSet border=\"0\" cols=\"*,0\">");
//document.write("<Frame height=\"100%\" frameborder=\"0\" width=\"100%\" src=\"/URLAsk\">");
//document.write("<Frame src=\"\">");
//document.write("</FrameSet>");
document.write("<body></body></HTML>");
</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
==============================================================
Hypertext Transfer Protocol
HTTP/1.1 302 Moved Temporarily\r\n
Location: http://auto.search.msn.com/response.asp?MT=testtest3&rov=&utf8\r\n
Content-Length: 0\r\n
Date: Fri, 13 Oct 2006 09:17:26 GMT\r\n
Server: Apache-Coyote/1.1\r\n
\r\n
==============================================================
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。

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。
