What Is Chrome.//net-internals/#dns?

Chrome://net-internals/#dns is a section within the chrome://net-internals tool that provides detailed information about Domain Name System (DNS) resolution in the Chrome browser. DNS resolution is the process of converting human-readable domain names (like example.com) into IP addresses (like 192.0.2.1) that computers use to communicate over the internet.

Within the chrome://net-internals/#dns section, users can access logs and statistics related to DNS resolution activities performed by the Chrome browser. This includes information such as DNS lookup times, the status of DNS queries, and the IP addresses associated with resolved domain names.

Some common use cases for chrome://net-internals/#dns include:

Troubleshooting DNS Issues

Users can review DNS lookup times and check for any errors or delays in resolving domain names. This can help diagnose connectivity problems or performance issues related to DNS.

Analyzing DNS Cache

Chrome maintains a DNS cache to speed up subsequent DNS lookups for frequently visited websites. Users can inspect the cache’s contents to see which domain names have been resolved recently and their associated IP addresses.

Monitoring DNS Prefetching

Chrome may prefetch DNS information for links on a web page to improve browsing speed. Users can monitor DNS prefetching activities to understand how Chrome proactively resolves domain names in the background.

Overall, Chrome.//net-internals/#dns provides valuable insights into the DNS resolution process within the Chrome browser, allowing users to diagnose and troubleshoot DNS-related issues effectively.

How Does Chrome://net-internals/#dns Work To Clear The DNS Cache On Chrome?

In chrome://net-internals/#dns, users can clear the DNS cache in Chrome by following these steps:

Accessing the DNS section: In the Chrome address bar, navigate to chrome://net-internals/#dns. This will open the DNS section of the Net Internals tool.

Clearing the DNS cache: Within the DNS section, locate the “Clear host cache” button. Clicking on this button will prompt Chrome to clear its DNS cache.

Clearing the DNS cache can help resolve DNS-related issues, such as outdated or incorrect DNS entries. It forces Chrome to perform fresh DNS lookups for domain names, ensuring that it retrieves the most up-to-date DNS information from the network. 

However, it’s worth noting that clearing the DNS cache may temporarily slow down browsing speeds for websites whose DNS information needs to be re-fetched.
