上海电信DNS劫持事件[含技术分析]

以上就是06年中上海电信所做的手脚了，其实对于如此行为我个人还是可以忍受的，因为第一我不会去装什么星空XXX，即使装了我也有办法不用你的东西。第二我不用MSN的搜索，你劫持了它对我没什么影响。然而，从最近一段时间的异常来看，事情显然已经不只是这个地步了，因为我在用各种浏览器各种搜索引擎的时候都碰到了被转向了114的情况，再加上我个人工作所维护的一些邮件服务器最近发现的怪异情况，我有理由怀疑上海电信在DNS上做了更令人不齿的行为。很不幸，我只是简单测试了一下，就发现确实如此，这次的行为可谓明刀明枪的抢劫了：

相信会用ping命令的网友们自然能看得懂这段输出的意思，简单来说，我ping了3个根本不存在的域名，本应出现找不到域名错误(hostname not found)，然而这显然不存在的3个域名竟然能得到解析结果，而无一例外的指向同一个IP----218.83.175.154。这个IP是什么我想大家应该也会非常有兴趣知道，点一下看看吧http://218.83.175.154。照样不能忘记把这个IP的whois信息拿出来作证据： http://www.dnsstuff.com/tools/whois.ch?ip=218.83.175.154 ，顺便贴出来：

ARIN says that this IP belongs to APNIC; I'm looking it up there.

铁证如山，看你上海电信还如何抵赖，目前我自己发现的出现问题的DNS服务器有202.96.209.5，202.96.209.6， 202.96.209.133，202.96.209.134，都为上海电信ADSL的DHCP默认指派的DNS，应该还有数个服务器应该也是类似，只是我没有去求证。

做为中国最大的ISP，发布广告无可厚非，但却打着官方的旗号公然破坏互联网基础设施，公然违反互联网RFC，真可谓给国内各大企业带了个好头，再加上CNNIC的流氓行为，中国互联网还有什么前途？！我作为IT网络业界的一个普通技术人员，对此现状真的感到深深的悲哀。

现在唯一还能让我高兴起来的事情，就是似乎这个转入到114查询的关键字似乎是随机选取的，经常会出现让人哭笑不得的结果，莫非电信的技术们也开始学习玩无厘头风格了？
