Sometimes our computer may encounter such a problem. Other computers in the same network can surf the Internet normally, but our computer encounters such a prompt: the page cannot be found and the DNS address of the server cannot be resolved. Do you know what to do if the computer prompts DNS error and can't surf the Internet? The following is some information about DNS error and inability to access the Internet, which I sorted out for your reference.
The computer prompts DNS error. The solution to not being able to access the Internet: set up computer DNS
When the computer encounters DNS failure, we can try to manually set up other DNS resolution services. There are already many public DNS in China, including Alibaba cloud DNS, baidu DNS, Google global DNS, etc. Here we recommend that you use Baidu or Alibaba cloud public DNS.
—& mdash; Alibaba cloud public DNS addresses (2): 223.5.5.5 and 223.6.6.6
—& mdash; Baidu public DNS address (1): 180.76.76.76
—& mdash; Google DNS address (2): 8.8.8.8 and 8.8.4.4
The method of setting up DNS on the computer is very simple. Many related tutorials have been shared for you before. The specific methods are as follows:
Right click the network icon in the lower right corner of the computer desktop, and then click to open the "network and sharing center" & mdash& mdash; Then click "change adapter settings" on the left. Next, right-click the name of the current network connection and select "properties". Finally, select "Internet Protocol version 4 (TCP / IPv4) / properties" in the network connection properties window, and then you can set DNS, as shown in the following figure.
In the figure above, we set the computer DNS as Alibaba cloud public DNS. This DNS is also universal in the world. Domestic users are preferred to recommend it. It has the functions of high-speed Internet access, anti phishing websites and so on.
The computer prompts DNS error and can't surf the Internet. The solution is to refresh DNS cache
After setting up the computer DNS, the computer may still not be able to access the Internet. This is mainly because the computer has a local DNS cache. It is necessary to refresh the DNS cache before correcting the previous DNS failure. The method of refreshing the DNS cache is as follows.
1. Use the windows + R shortcut key combination to open the running dialog box, then type the [CMD] command, and then click "OK" below, as shown in the figure below.
2. In the CMD command box that opens next, enter the run command: [ipconfig / flushdns] (after entering, press enter to run) to refresh the local DNS cache, as shown in the following figure.
If the computer fails to access the Internet due to DNS errors, you can successfully repair the Internet according to the above methods.
