这篇文章出自一个对专业知识十窍通九窍的普通网民之手，专业的看到别笑话。域名劫持应该是最近一个比较热门的话题了吧，电信、网通相继开始利用自己的垄断地位明目张胆的劫持域名，GOOGLE上有187,000项符合域名劫持的查询结果，对ISP的域名劫持还没有什么完美的解决方案，就说说本人解决的过程吧。

首先，我立刻想到换DNS， GOOGLE了下，结果自己不知道用什么关键词，于是想到直接用根DNS，直接GOOGLE到如下，PING值是本人的，四川电信小区宽带，圆括号内为拥有组织，数据采自www.who.is和APNIC

注意啦，众所周知现在投入使用的域名根服务器只有1个，也就是说n.root-servers.net是不存在的，本应该返回Name does not exist，现在被劫持到电信的114搜索去了。然后给电信的vnet.cn带来可观的流量（感兴趣的ALEXA一下就知道了）。然后我就选了192.5.5.241和192.36.148.17这两个PING值比较低的DNS，然后改拨号连接的DNS，然后就无法正常上网了， nslookup一下，得到这样的结果。

Server: [192.5.5.241]
Address: 192.5.5.241 Name: cxlyx.cn
Served by:
- NS.CERNET.NET
202.112.0.44

203.119.29.1
cn 突然想起根DNS只负责浏览器.com和.net的解析。。然后换上国内的DNS，203.119.25.1和203.119.26.1，还是无法解析。。得到结果如下（我一直用EDITDNS.NET提供的免费DNS解析，比国内的新网、万网好用多了，记录条数无限） Server: [203.119.25.1]

Address: 203.119.25.1 Name: cxlyx.cn
Served by:
- ns4.editdns.net cxlyx.cn
- ns2.editdns.net cxlyx.cn 再换，用EDITDNS解析，自己的网站可以访问了，但不在EDITDNS的域名无法解析。。因为EDITDNS的DNS只负责自己的域名，别人的直接扔给你一句209.188.10.80 can’t find 163.com: Query refused，因为它不是ISP提供的那种（我也不知道怎么表达。。）无奈。。莫非，只有忍受？突然想起既然可以通过根DNS>.cn的DNS>cxlyx.cn的DNS这样一步步的查找到记录，那么自己架一个DNS就得了。这下就简单了，直接取GOOGLE，得到BIND，却是LINUX用的，不具备可操作性。。继续G，终于找到需要的了（点击图片进入下载页）：

虽然是15天试用版，不过是全功能的，满了15天用偷天换日就可以继续用了设置都可以不管它（默认状态下只给自己提供解析），安装完直接运行就行了 ^_^ 然后把DNS设置成127.0.0.1和自己的内网或公网IP（我的是内网192.168.0.2）

现在终于可以正常的返回Server Not Found了
