Tools/raw Materials

Windows Xp/vista


Fsat DNS (recommended)

noun explanation

DNS: Baidu Encyclopedia to me the explanation is-------DNS is the name System (domain name systems) abbreviation, it is composed of parser and domain name server. A domain name server is a server that holds the domain name and corresponding IP address of all the hosts in the network and has the ability to convert domain names to IP addresses. Where the domain name must correspond to an IP address, and the IP address does not necessarily have a domain name.

In fact, we usually visit the website, for example, we visit Baidu, then we enter www.baidu.com in the browser and then through the network, through the parser and domain name server translation conversion, We have successfully access to this Baidu's real IP address, so from here we can also see that if the DNS error or set the error, then we will not be able to successfully access this page, even if the occasional access to the words are very slow to open very slowly. In this experience, setting up DNS is the IP address of the DNS server.


In general, we do not have to set up DNS, the system by default is in the state of automatic acquisition.

XP Viewing method: Start------Control Panel-----Network connection-------Local Area Connection-----Properties------Internet Protocol (TCP/IP)------Properties we can see the default settings.

Vista View method: Start-----Control Panel------Network and Share Center-----Point the View status-------properties after the local connection--------Internet Protocol 4 (TCP/IPV4)--------properties and then you can see it.

(This is my own set, so not automatically get the option)

If we find that we are prompted for DNS errors automatically, then we need to manually set the correct DNS address to the system. Select "Use the following DNS server address", and then fill in the address you get is OK, generally we fill in two, a preferred DNS server address, an alternate DNS server address (this can not fill in).

Above my two IP address is Shanghai Telecom's DNS server address, everyone can according to their own location broadband operators of the actual DNS server address settings, if you use the same as me is Shanghai Telecom Broadband, then you can set up and I like. Set it up and then make sure. Then you can rerun your browser to check the effect. General hint DNS error or can only QQ can not access the Web page problem will be resolved (sometimes because of IE problems can not access the Web page problem, we can set the Internet properties of the last page to reset IE).

The above method is good for a friend who is fixed in the Internet in a region, but for some people who travel frequently or often go to different places, such fixed after more trouble, change a province will manually change a DNS address, then I here for you to introduce a small software, named Treewalk, Can achieve native DNS resolution, after downloading double-click will automatically decompression and installation, after installation will automatically set your preferred DNS for,

Then in your computer's service will be more than one Treewalk DNS service, if you want to stop the service, you do the following: Start-----All Programs------treewalk-----Service-----Stop DNS Service can ~ ~ ~ Select the Start DNS service if you want to turn on the service.
