Having trouble with your website? One troubleshooting step you might need to take is flushing the Domain Name System (DNS) cache on your Linux device. This quick and easy process will help you clear your cache and resolve any issues you may be facing. In this guide, we’ll walk you through the steps to flush the DNS cache on Linux, ensuring a smooth browsing experience. Let’s get started!
What is DNS Cache?
Before we dive into the steps, let’s quickly understand what DNS cache is. Similar to web browsers, operating systems store cache files of previous DNS lookups in what is called the DNS cache. This cache speeds up the DNS lookup process by resolving domains to their IP addresses, ultimately making web pages load faster.
Reasons to Flush DNS Cache periodically
Now that we know what DNS cache is, let’s explore why it’s important to flush it periodically:
- Prevent tracking of browsing behavior: Flushing DNS records helps protect your privacy by making it difficult for hackers to track your browsing history.
- Enhance security: Outdated or corrupted DNS cache files can be vulnerable to DNS spoofing, risking the exposure of sensitive information.
- Solve technical problems: Flushing the DNS cache ensures that your operating system checks for updated DNS records, helping resolve connection issues and display web content correctly.
How to Flush DNS Cache on Linux
Now, let’s get to the step-by-step process of flushing the DNS cache on Linux:
Step 1: Open the terminal
Press Ctrl+Alt+T
keys together to open the terminal window on your Linux device.
Step 2: Clear the DNS cache
Enter the following command in the terminal to clear the DNS cache:
sudo systemd-resolve –flush-caches
Step 3: Confirm cache clearance
To ensure that the DNS cache has been successfully flushed, run the following command:

After executing these steps, your DNS cache will be cleared, and you’ll be ready to continue your troubleshooting process.
Final Words
Flushing the DNS cache on Linux is a simple process that can have a significant impact on your browsing experience.
