How to Clear DNS Cache

When accessing websites, DNS cache helps us quickly find the correct IP address, so that web content can be loaded quickly. However, sometimes we need to clear DNS cache to get the latest IP address. Here are some common ways to clear DNS cache.

Clearing DNS Cache on Windows

For Windows users, the method to clear DNS cache is as follows:

Open command prompt (cmd). You can find it in the Windows search bar.

Type the command “ipconfig /flushdns” in the command prompt.

Press enter and wait a few seconds until you see the message “Windows IP configuration successfully flushed the DNS resolver cache.”

This completes the clearing of DNS cache.

Clearing DNS Cache on Mac OS

For Mac OS users, the method to clear DNS cache is as follows:

Open the Terminal application. You can find it in the “Utilities” folder of Mac OS.

Type the command “sudo killall -HUP mDNSResponder” in the Terminal.

Press enter and wait a few seconds until the command is executed.

This completes the clearing of DNS cache.

Clearing DNS Cache on Linux

For Linux users, the method to clear DNS cache is as follows:

Open the Terminal application.

Type the command “sudo /etc/init.d/nscd restart” in the Terminal.

This completes the clearing of DNS cache.

Conclusion

Clearing DNS cache is simple and can help us get the latest IP address, thus solving problems such as inability to access some websites. If you often encounter problems accessing websites, you can try clearing DNS cache and check if you can access them.
