No doubt webmaster is often to visit foreign websites, one of the groups, below the foreign website to visit the big speed-increasing skills to help you save time.

The primary role of the DNS server is to resolve the domain name, it is like a translator, when we send a URL from the browser address bar, we first have to convert the URL to a real IP address to access the site. So as a middleman, the response speed of the DNS server can also affect the speed of the Internet.

We know that DNS resolution is also a big reason to determine the speed of the network. If you always find yourself manually and configure a faster DNS server, it's really troublesome that the comet DNS optimizer. This can be done intelligently: it provides 2000 or so alternate DNS, and can be one-click speed and choose the fastest DNS as a native DNS server. After you start the program, click "Action → one key complete (recommended)". The program automatically writes the fastest-test DNS to the settings in the network connection, and then opens the network connection → support → details to see multiple DNS addresses.

In addition, you can also use Google launched the "Namebench", start the program after clicking "Runing", the program will automatically speed up the 200 DNS, and give specific test results, we just press the prompt to enter the fastest DNS server address on it.

Secure Internet access using Google public DNS

The fastest DNS can be found by this method, but the fastest does not mean the most stable. Stable DNS, or to recommend Google's free "Google public DNS" service, its server IP address is 8.8.8.8 and 8.8.4.4. Open Control Panel → network and Internet connections, right-click the current network connection (such as ADSL) select Properties → general →internet Protocol (TCP/IP). Then click properties → general, and select Use the following DNS server, and the preferred DNS server and alternate DNS server Enter the Google public DNS address in turn. If you want to use the default DNS, simply select "Automatically obtain DNS server address" again.

The use of Google DNS, to visit foreign sites, speed up the effect is more obvious, and the domestic site does not have much effect, so it is more suitable for frequent visits to foreign web friends use.

The Internet worry-free, judge the DNS service fault

There are times when clearly their own network is no problem, you can use QQ but cannot open the page, prompted "Internet Explorer can not display the Web page", this time is very likely that the DNS service failure (because QQ directly use IP address to the server, without DNS resolution). DNS failures can be judged by the "nslookup" commands that come with the system.

When you start a command prompt and enter "nslookup", the DNS server address used by the current system is displayed on the screen, and the "Default servers are not available" prompt is returned if the current DNS fails. Indicates that DNS is not available. Continue to enter inaccessible URLs such as www.b0d.cn and return the "DNS Request timed out" prompt. At this point we can customize the available DNS using the methods described above.

Can you really speed up after using the fastest DNS? First open IE8 in the default DNS settings and select "Delete browser history when exiting" in the general option to avoid the time error of opening the Web site due to caching. Then open http://webwait.com in IE, an online speed-measuring tool that uses AJAX technology to load the page and record the time it takes to load it through an analog browser. In this screen, enter http://www.cnn.com, http://www.aol.com, http://www.pcplus.co.uk (a British magazine website I like very much) to test. Then turn off IE8 to empty the cache, run the comet DNS optimizer to use the fastest DNS, ditto re test again. Test results before and after the use of the fastest DNS, the full opening of the above URL can save about One-third time (the default DNS under the average time is 25, 30, 47 seconds, optimized for 16, 21 and 29 seconds).
