  • 家园 【请教】连不上国内的站点

    兄弟在悉尼,最近突然连不上国内的一些站点。比如www.sina.com.cn 还有 www.sohu.com

    可以ping通

    ping www.sina.com.cn

    Pinging libra.sina.com.cn [61.135.152.82] with 32 bytes of data:

    tracert也没问题

    但是用浏览器登陆新浪会返回下面的网页:

    The requested URL could not be retrieved

    While trying to retrieve the URL: http://www.sina.com.cn/

    The following error was encountered:

    Unable to determine IP address from host name for sports.sina.com.cn

    The dnsserver returned:

    Timeout

    This means that:

    The cache was not able to resolve the hostname presented in the URL.

    Check if the address is correct.

    Your cache administrator is webmaster.

    Generated Mon, 04 Apr 2005 13:05:50 GMT by 06.cdn.mykenae.com (squid/2.5.STABLE5)

    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?
