关于微软的DNS记录似乎不正确，莫非被黑客攻击了？？？
事情的经过是这样的：
我用netstat看总是有到a61-200-81-150.deploy.akamaitechnologies.com 80端口的连接。用Active Ports看是msnmsgr.exe进程发起的连接。开始以为是MSN Messenger被病毒感染，用Norton Antivirus最新版杀毒，没有发现病毒。重新从微软的网站上重新下载MSN Messenger，安装后还是会出现到a61-200-81-150.deploy.akamaitechnologies.com的连接。
a61-200-81-150.deploy.akamaitechnologies.com的IP地址是：61.200.81.150.
在APNIC上查得此地址是日本的。
inetnum: 61.200.0.0 - 61.215.255.255
netname: JPNIC-NET-JP
descr: Japan Network Information Center
country: JP
我们公司组建有自己的DNS服务器，解析本公司自己的域名，对于不能解析的使用转发器。在转发器中使用了四个DNS服务器地址：
202.112.80.106 （北京师范大学DNS服务器）
202.106.0.20 （北京网通DNS服务器）
202.106.196.115 （北京网通DNS服务器）
202.96.199.133 （北京的DNS服务器，具体归谁管不清楚）
继续讲：
我想既然它要连接61.200.81.150，那我就在防火墙上把这个IP地址的C段给它封了。可是在封了之后发觉search.microsoft.com无法访问。用nslookup查search.microsoft.com的A地址，得到结果如下：
Non-authoritative answer:
Name: a134.g.akamai.net
Addresses: 61.200.81.150, 61.200.81.142
Aliases: search.microsoft.com, search.microsoft.akadns.net
search.msn.com.edgesuite.net
而此前已经查得些地址不是微软的地址，于是开始怀疑我公司的DNS被修改了。检查之后没有发现问题。
又在我公司DNS服务器上设置的四个转发址中查询得到结果如下：

61.200网段已经确认非微软所有，指向的是日本。
下面是从另外三个DNS服务器上得到的IP地址的查询结果：

从以上结果可以看出search.microsoft.com极可能被指向了错误的地址。一个网站不可能跨这么多的网段的。
而从国外的一个网站www.dnsstuff.com上查得的www.microsoft.com的IP地是207网段的。用查得的IP地址是直接可以访问到微软的主页。而如果用search.microsoft.com查到的IP地址是不能访问search.microsoft.com的主页，而这个主页确实存在，我经常上去看。
大家说是什么原因造成的？？？
