How to solve the problem of dns network server not responding

DNS (Domain Name System) is a system that converts domain names into IP addresses. It plays an important role in the Internet. When we browse the web or use network services, we sometimes encounter the problem of DNS server unresponsiveness. This article will discuss the causes and solutions of DNS network server not responding.

First, let’s take a look at the possible reasons why the DNS server is not responding. Generally speaking, there are mainly the following aspects:

1. Network connection problem: The DNS server not responding may be due to a problem with your network connection. This could be caused by a lack of connectivity at your router, modem, or network. In this case, you can try restarting these devices and make sure they are working properly.
2. DNS setting error: If the DNS settings of your computer or router are incorrect, the DNS server will not respond. You can check your network settings to make sure the DNS server IP address is configured correctly.
3. DNS server problems: Sometimes, the DNS server itself may have problems, such as overload, downtime, or misconfiguration, etc. In this case, you can only wait for the server to come back to normal and try to use another reliable DNS server.

Next, let’s discuss how to solve the problem of DNS server not responding.

1. Check network connection: First, you can check whether your network connection is normal. You can try restarting routers, modems, and other devices and make sure their power, connections, and settings are all normal.
2. Check DNS settings: If your computer or router's DNS settings are incorrect, you can try changing them. In Windows systems, you can open "Control Panel", then select "Network and Internet", then "Network and Sharing Center", select "Change Adapter Settings" in the left navigation menu, and then find the network you are using To connect, right-click and select "Properties". Next, in the "Internet Protocol Version 4 (TCP/IP)" or "Internet Protocol Version 6 (TCP/IP)" option, select the "Properties" button, and in the pop-up dialog box, select "Use the following DNS server address ” and enter the correct DNS server address. When finished, click OK to save changes.
3. Use a public DNS server: If your custom DNS server does not solve the problem, you can try to use some public DNS servers, such as Google's public DNS servers (8.8.8.8 and 8.8.4.4) or OpenDNS wait. These public DNS servers are often more stable and can solve the problem of DNS server unresponsiveness. You can change the DNS server address in the network settings of your computer or router, and then restart the network device.
4. Clear DNS cache: Sometimes, DNS server unresponsiveness may be due to DNS cache issues. In Windows systems, you can press the Win R key to open the run window, then enter "cmd" and press the Enter key to open the command prompt window. In the command prompt window, enter the "ipconfig /flushdns" command and press Enter to clear the DNS cache. You can then try to access your target website to see if the problem is resolved.

To summarize, the problem of DNS server unresponsiveness may be caused by multiple factors. We can solve this problem by checking the network connection, DNS settings and using public DNS servers. Therefore, when encountering the problem of DNS server unresponsiveness, do not panic. You can check and solve it one by one according to the above methods to ensure the normal operation of the network.
