How to Flush DNS Cache on Google Chrome: A Step-by-Step Guide

DNS (Domain Name System) is an essential component of the internet that translates human-readable domain names into IP addresses, enabling browsers like Google Chrome to locate websites. Sometimes, DNS issues can cause problems with website access or slow loading times. To resolve such issues, flushing the DNS cache on Google Chrome can be a quick and effective solution. In this blog, we'll walk you through the process of flushing DNS cache on Chrome.

What is DNS Cache and Why Flush It?

DNS cache is a temporary storage area on your computer that contains recently resolved domain names and their corresponding IP addresses. By storing this information locally, the browser can quickly access websites you've recently visited without having to query the DNS server repeatedly. However, occasionally, the cache may become outdated or corrupted, resulting in incorrect or failed website resolutions. Flushing the DNS cache helps clear this local memory and forces Chrome to retrieve updated DNS information, ensuring smoother browsing experiences.

Step-by-Step Guide to Flush DNS Cache on Chrome:

Step 1: Open Google Chrome: Launch the Google Chrome browser on your computer if it's not already open.

Step 2: Access the Chrome Flags Page: In the address bar, type "chrome://flags" (without quotes) and press Enter. This will take you to the Chrome Flags page where you can access experimental features.

Step 3: Search for "DNS Over HTTPS": On the Chrome Flags page, you'll find a search box. Type "DNS Over HTTPS" (without quotes) into the search box to quickly locate the DNS-related settings.

Step 4: Enable "Secure DNS lookups": Once you find the "Secure DNS lookups" option, click on the drop-down menu next to it, and select "Enabled." This option enables the DNS over HTTPS feature, which helps improve privacy and security while performing DNS resolutions.

Step 5: Relaunch Chrome: At the bottom of the Chrome Flags page, you'll see a prompt to relaunch the browser to apply the changes. Click on the "Relaunch" button to restart Chrome.

Step 6: Verify DNS Over HTTPS is Enabled: After Chrome relaunches, go back to the Chrome Flags page by typing "chrome://flags" in the address bar. Search for "Secure DNS lookups" again to ensure it shows "Enabled."

Step 7: Clear DNS Cache: Now that DNS over HTTPS is enabled, it's time to clear the DNS cache. In the Chrome address bar, type "chrome://net-internals/#dns" and press Enter. This will take you to the DNS cache page.

Step 8: Clear the DNS Cache: On the DNS cache page, click on the "Clear host cache" button. This action will flush the DNS cache on Google Chrome.

Step 9: Restart Chrome: Finally, close and reopen Chrome to complete the process. Your DNS cache should now be cleared, and Chrome will begin using the updated DNS information for website resolutions.

Conclusion: Clearing the DNS cache on Google Chrome can help resolve browsing issues related to outdated or corrupted DNS information. By following the step-by-step guide provided in this blog, you can quickly flush the DNS cache and ensure smoother and more reliable browsing experiences. Keeping your DNS cache up-to-date is an essential practice to maintain optimal internet performance, and it's just one of the many ways you can optimize your browsing experience. Happy browsing!
