DNS resolution problems, what should I do if DNS resolution fails?

Home broadband is generally connected to the Internet through virtual dial-up, and the operator's routing equipment allocates IP and provides DNS.

When the host connects to the network, it is resolved through local routes or broadband DNS, and filling in DNS can help resolve the problem directly, without going through local routes.

Write the DNS of the domain name provider.

After the domain name is registered, the domain name provider will automatically assign a set of DNS to you, and you can log in to the domain name resolution panel to resolve it directly, and you generally do not need to set up DNS by yourself.

Hope it helps. （53dns）

Generally, your network service provider's switches, routers and other equipment will automatically assign a DNS address for users to automatically obtain, but some DNS servers are not effective or have more problems, so some users will turn off automatic acquisition in the connection attributes to enable manual settings, such as if you want to manually set up by yourself, it is recommended that you.

The function of DNS is to translate the ** you enter into the IP address or the IP address to **,If you don't want to open a web page with this thing, you can only make a small book like a long time ago to record the IP addresses of each**,And then check them one by one。。。 Therefore, if some people can log in to QQ but can't open the web page, it is likely that it is a DNS problem.

It may be that the ** address is wrong, which means that the record corresponding to this address cannot be found.

Summary. Hello dear, happy to answer your <>

If a DNS resolution failure occurs, there are several ways to try to resolve it: <>1Check your network connection and restart your router:

If your network connection is abnormal or the network device is faulty, DNS resolution may fail. You can try reconnecting to the internet or restarting your router to see if that resolves the issue. 2.

Change DNS server: DNS resolution may be prevented due to a failure of the DNS server you are using or network congestion. You can change to another reliable DNS server (e.g., Google's public DNS server or 114DNS).

3.Clear DNS cache: Due to the existence of DNS cache, DNS resolution can sometimes be problematic.

You can try clearing the DNS cache to allow the system to retrieve the latest DNS records. Under the Windows operating system, you can open the command prompt and enter"ipconfig /flushdns"Clear the DNS cache.

Kiss, and that's <>

4.Check your firewall settings or security software settings: Your firewall or security software may be blocking DNS resolution, so you can try adjusting your firewall or security software settings.

5.Contact the network service provider: If the DNS resolution failure still exists, you can contact the network service provider for consultation and handling.

Check if the network connection is working: Make sure that your device is connected to the Internet, and you can try to reconnect to Wi-Fi or change the network connection method. 2.

Clear DNS cache: You can enter it in the command prompt"ipconfig /flushdns"to clear the DNS cache, which may help resolve some DNS resolution issues. 3.

Change the DNS server address: You can try changing the DNS server address, for example using Google's public base DNS server address: and, or using another third-party DNS server.

4.Check your firewall settings: Some firewall settings may block DNS requests, you can try turning off your firewall or modifying your settings to allow DNS requests.

In general, there may be many causes of DNS resolution delay failures, which need to be analyzed on a case-by-case basis, and the above are some common solutions. In addition, understanding the principles of DNS and related code Zenxiang knowledge can also help you better understand and solve DNS resolution failures.

Method 1: Clear the local DNS cache

Although the DNS on the general computer is automatically obtained, but occasionally there will be a ** inaccessible, but other users are normal, for this situation, it is likely that the DNS cache error of our computer is caused by Liangtuanhui, and the solution is very simple, as long as the DNS cache is emptied.

Since we all know that our computer obtains the DNS server address of the nearest network provider by default, but sometimes, the DNS server of the nearest network provider may have some minor problems, such as some lines are blocked, etc., resulting in some ** inaccessibility. In this case, we can manually set the DNS server address to the DNS server address of other peripheral network providers.
