Why and How to Access chrome net-internals dns in Chrome

The URL chrome://net-internals/#dns in Google Chrome opens a powerful diagnostic page that lets users view, troubleshoot, and clear the browser's DNS cache. This tool is useful for fixing website loading issues, slow browsing, and DNS resolution errors by managing the DNS entries Chrome stores to speed up domain name lookups.

What is chrome://net-internals/#dns?

The page chrome://net-internals/#dns is an internal Chrome tool designed to provide detailed insights into the browser's Domain Name System (DNS) behavior. DNS translates website domain names into IP addresses required for connecting to servers. Chrome caches these DNS entries to speed up browsing, but sometimes cached entries become outdated or corrupted, causing connectivity or loading problems. This page allows users to inspect and clear these cached DNS records.

Why Use chrome://net-internals/#dns?

Chrome caches DNS records for performance improvement. However, when DNS changes occur on a website or errors happen, cached entries can lead to:

* Websites not loading properly

* Slow page load times

* Incorrect redirects or errors

Accessing chrome://net-internals/#dns enables users to clear and refresh the DNS cache inside Chrome without restarting the whole system. This aids in troubleshooting and improving browsing experience promptly.

1. Open Google Chrome on Windows, macOS, Linux, or other supported platforms.

2. Type chrome://net-internals/#dns in the address bar.

3. Press Enter to open the DNS cache management interface.

4. Here, users see a list of cached domain names and their corresponding IPs along with time-to-live (TTL) values.

How to Clear the DNS Cache Using chrome://net-internals/#dns

1. Follow the access steps above to reach the DNS page.

2. Click the “Clear host cache” button visible on the page.

3. After clearing, it is recommended to navigate to chrome://net-internals/#sockets and click the button to flush the socket pools, which completes the refresh process.

4. Restart Chrome for the changes to take full effect.

Key Features of the DNS Internals Page

* Enhancing browsing speed and reliability when DNS delays or errors happen.
