How to Clear Host Cache in Chrome (DNS Cache)


Google Chrome’s DNS cache, also known as the host cache, stores information about previously visited websites to facilitate faster loading times and smoother browsing experiences. However, outdated or corrupted cache entries can sometimes cause connectivity issues, DNS resolution errors, or website loading problems. In this article, we’ll explore the importance of clearing the host cache in Chrome and provide step-by-step instructions on how to do it effectively.

Understanding Chrome's Host Cache

Understanding Chrome’s Host Cache

Chrome’s host cache, or DNS cache, plays a crucial role in speeding up the browsing process by storing DNS mappings for recently visited websites. When you visit a website, Chrome first checks its host cache to see if it has a stored IP address for the corresponding domain name. If a matching entry is found in the cache, Chrome can skip the DNS lookup process and directly connect to the website’s server, saving time and reducing latency.

However, over time, the host cache can become cluttered with outdated or invalid entries, leading to issues such as:

1. Slow website loading times

2. DNS resolution errors

3. Connection problems to certain websites

4. Inconsistent browsing experiences

Clearing the host cache in Chrome is a simple yet effective way to address these issues and ensure smooth and reliable browsing performance.

Steps to Clear Host Cache in Chrome

1. Open Google Chrome:

Launch the Google Chrome browser on your computer. Ensure that you are using the latest version of Chrome to access the most up-to-date features and improvements.

2. Access Chrome’s Settings:

Click on the three-dot menu icon in the top-right corner of the Chrome window to open the browser’s main menu. From the dropdown menu, select “Settings” to access Chrome’s settings page.

3. Navigate to Privacy and Security:

In the Chrome settings page, scroll down to find the “Privacy and Security” section. Click on this section to expand it and reveal additional options.

4. Clear Browsing Data:

Within the “Privacy and security” section, locate and click on the “Clear browsing data” option. This will open the “Clear browsing data” menu, which allows you to delete various types of browsing data, including the host cache.

5. Select the Time Range:

In the “Clear browsing data” menu, you’ll see a dropdown menu labeled “Time range.” This allows you to choose the time period for which you want to clear browsing data. To clear the entire host cache, select “All time” from the dropdown menu.

Choose Browsing Data Types

6. Choose Browsing Data Types:

Below the time range dropdown menu, you’ll see a list of checkboxes corresponding to different types of browsing data. To clear the host cache, ensure that the checkbox next to “Cookies and other site data” is checked. You can also choose to clear other types of data, such as browsing history and cached images and files if desired.

7. Clear Data:

Once you’ve selected the time range and browsing data types you want to clear, click on the “Clear data” button to initiate the clearing process. Chrome will then proceed to clear the selected browsing data, including the host cache.

8. Restart Chrome:

After clearing the host cache, it’s a good idea to restart Google Chrome to ensure that the changes take effect. Close the browser window and relaunch Chrome to begin browsing with a fresh host cache.

Benefits of Clearing Host Cache in Chrome

1. Improved Browsing Performance: Clearing the host cache in Chrome can help improve browsing performance by eliminating outdated or invalid cache entries that may cause connectivity issues or slow loading times.

2. Enhanced Security: Regularly clearing the host cache can help mitigate security risks associated with cached data, such as cookie tracking or session hijacking.

3. Troubleshooting Network Issues: If you’re experiencing DNS resolution errors or connection problems to certain websites, clearing the host cache can often resolve these issues by forcing Chrome to perform fresh DNS lookups.

4. Ensured Privacy: Clearing the host cache ensures that no remnants of your browsing history or website data are stored locally on your computer, enhancing your privacy and security while browsing the web.
