联通的DNS真是没有节操

家里使用的是联通的宽带,一直使用的也是联通的DNS.

最近在chrome里搜索,无论搜索什么东西,都会弹出这么一个东西出来:

Did you mean to go to 一个乱七八糟的网址。点击进去之后,是联通的一个网页导航的网站。

下面这个连接有详细的解释:

It's not really Chrome's fault. Chrome is just looking up what you typed in the address bar as though it were the name of a server, and if it finds something, it offers to take you there. If not for this feature, there would be no way to access the host named "tubes" (for example) on your local network. 

The problem is that your ISP is running a domain "helper" that responds in the affirmative to every server it's asked about. So when Chrome asks if 'tubes' exists, your ISP is saying, yes, I've got that right here. If you click on the omnibox, I strongly suspect that you'll be taken to a landing page owned by your ISP. 

If you don't like this behavior, you can sometimes turn it off with a control panel somewhere in your ISP's settings (on Comcast, for example, there's a link from the landing page). You can also configure your computer to use Google's public DNS, avoiding your ISP's DNS games entirely: http://code.google.com/speed/public-dns/docs/using.html

把路由器上缺省的DNS改成了114.114.114.114 和阿里的223.6.6.6,问题就解决了
