但是用浏览器登陆新浪会返回下面的网页:

While trying to retrieve the URL: http://www.sina.com.cn/
The following error was encountered:

比较迷惑,好象说我的dns服务器有问题,于是我除了用isp提供的两个dns地址外,又添加了3个备用dns,如下:
DNS Servers . :
220.233.0.4
220.233.0.3
139.134.2.2
192.189.54.33
137.222.10.36
结果都一样,都到上面的页面。
不解1:是不是dns的问题?因为我ping www.sina.com.cn时,是能够解析成ip地址的啊。但到浏览器就不行了,ie和firefox都试过。
不解2:我的isp是exetel.com.au,为啥连不上时都是 mykenae.com generated的页面啊?
