Chrome.//Net-Internals/Dns Clear: A Compressive Guide

Introduction: Chrome.//Net-Internals/Dns Clear

Google Chrome stores DNS (Domain Name System) records locally to speed up browsing by reducing the time it takes to resolve domain names to IP addresses. If you’re experiencing DNS-related issues or need to refresh DNS records, clearing the DNS cache can be helpful. Here’s how to clear DNS cache in Google Chrome:

Steps to Clear DNS Cache in Google Chrome

  1. Open Chrome Settings:
    • Click on the three dots (Menu) in the upper-right corner of Chrome.
    • Select “Settings” from the dropdown menu.
  2. Access Chrome’s Internal Tools:
    • In the Settings tab, scroll down and click on “Privacy and security” in the left-hand menu.
    • Click on “Clear browsing data.”
  3. Clear Browsing Data:
    • In the Clear browsing data window, ensure that “Basic” is selected at the top.
    • Choose the time range from which you want to clear data. Select “All time” to clear everything.
    • Check the box next to “Cookies and other site data.”
    • Check the box next to “Cached images and files.”
    • Optionally, you can uncheck other boxes if you only want to clear DNS cache.
    • Click on “Clear data.”
  4. Verify DNS Cache Clearance:
    • After clearing, you can verify if the DNS cache has been cleared by visiting “chrome://net-internals/#dns” in your Chrome browser.
    • Look for the “Clear host cache” button at the top of the page and click on it to ensure the cache is cleared.

Why Clear DNS Cache?

  • Resolve DNS Issues: Clearing the DNS cache can resolve issues where websites fail to load due to incorrect or outdated DNS information.
  • Improve Browsing Performance: By clearing the cache, Chrome will fetch fresh DNS records, potentially improving browsing speed and accuracy.

Advanced Users: Using chrome://net-internals/#dns

  • For more advanced users, you can directly access Chrome’s internal DNS cache management by entering “chrome://net-internals/#dns” in the address bar.
  • From this interface, you can monitor DNS activity, view cached entries, and clear the DNS cache using the provided tools.

Tips for Optimal Performance

  • Regular Maintenance: Consider clearing DNS cache periodically to ensure smooth browsing experience and accurate domain resolutions.
  • Security Considerations: Clearing cache may expose you to slightly slower browsing initially as Chrome fetches new DNS records. It’s a trade-off between performance and accuracy.


Clearing DNS cache in Google Chrome is a straightforward process that can help resolve connectivity issues and optimize browsing performance. By following these steps, you can effectively manage DNS cache and ensure a smoother browsing experience in Chrome.
