In the process of daily use of the computer, we may encounter some network connection problems, such as not being able to access a specific ** or the domain name resolution is abnormal. In this case, clearing the DNS cache is a common workaround. This article will dive into the ** why you should clear your DNS cache, as well as how efficient your Mac is to clear your DNS cache.
The necessity of mac to clear dns cache
1.Resolve domain name issues.
DNS (Domain Name System) is responsible for translating domain names into corresponding IP addresses, enabling us to access specific ** through domain names. The DNS cache records the previous domain name resolution results, but sometimes these caches may be out of date or inaccurate, causing access issues. Clearing the DNS cache ensures that you get the most up-to-date DNS information.
2.Fixed access specific issues.
Sometimes, due to the wrong IP address information stored in the DNS cache, it may result in the inaccessibility of a particular **. Clearing the DNS cache for MAC can help fix these issues and regain the correct DNS results.
3.Speed up the domain name resolution process.
Clearing the DNS cache can cause the system to query the domain name again to obtain the latest IP address information. This can help speed up domain name resolution, especially when the network switches or the domain name information changes.
4.Adapt to network changes.
When you switch network environments, the original DNS cache may no longer be applicable. Clearing the DNS cache by MAC ensures that the correct domain name resolution results are obtained in the new network environment and avoids connection problems caused by cache expiration.
Ways to clear DNS cache for Mac
Mac clearing DNS cache is not complicated, and there are several easy ways to achieve it. Here are some commonly used ways to clear DNS cache:
1.Use terminal commands.
Open the terminal app, enter the following command and press enter
sudo killall -hup mdnsresponder
You may be asked to enter your administrator password to confirm the action. This command will clear the DNS cache and restart the mdnsresponder service.
2.Use System Preferences.
Open "Settings" and go to the "Network" option.
Select the currently active network connection (Wi-Fi or Ethernet).
Click on the "Details" button in the bottom right corner.
Switch to the DNS tab.
Click the "-" button below to delete the existing DNS server.
Click the "OK" button in the bottom right corner.
This method forces the system to flush the DNS cache by manually changing the DNS server settings.
3.Use the GUI tools.
Aside from terminal commands and system preferences, there are also some third-party tools like CleanMyMac X. Provides a graphical interface operation for clearing the DNS cache. CleanMyMac X is more intuitive and easy to use, suitable for users who are not familiar with using terminal commands, and the steps to clear DNS are as follows:
Open the software, click [Maintenance], and view the tasks
Select "Refresh DNS cache" and click the "Run" button. At this point, Mac clearing DNS cache is done, the process is intuitive and simple!
At this point, Mac clearing DNS cache is done, the process is intuitive and simple!
Conclusion
Clearing the DNS cache for Mac is an effective way to solve network connection problems, especially when encountering domain name resolution exceptions and inaccessibility to specific **. On Mac, users can easily do the DNS cache clearing operation by using terminal commands, System Preferences, or CleanMyMac X. Clearing the DNS cache not only helps resolve network issues, but also improves the speed and accuracy of domain name resolution, ensuring that the system is running optimally.
