Step by Step Tutorial on chrome net-internals dns in Google Chrome

The chrome://net-internals/#dns page is a powerful diagnostic tool in Google Chrome that allows users to view and clear the browser's DNS cache. By managing this cache, users can troubleshoot and resolve DNS-related browsing issues such as slow page loads, incorrect website redirection, and DNS lookup errors. Clearing Chrome’s DNS cache can refresh outdated or corrupted DNS records, improving your browsing performance and resolving connectivity problems.

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

The chrome://net-internals/#dns is a built-in internal page within Google Chrome that provides detailed information about how the browser manages DNS (Domain Name System) resolutions. It shows cached DNS entries—the records of domain names mapped to IP addresses stored temporarily by Chrome to speed up website access.

This tool is mainly used to view, diagnose, and clear the DNS cache to fix network and browsing issues caused by outdated or corrupt DNS records.

Understanding DNS and DNS Cache

DNS is the internet’s phonebook, converting human-friendly domain names like www.google.com into IP addresses which browsers need to load websites. Chrome caches these DNS lookups to avoid repeatedly querying DNS servers, enhancing speed.

However, this cache can sometimes hold outdated or incorrect data, leading to problems such as website loading failures, slow browsing, or domain name conflicts. Clearing the DNS cache forces Chrome to fetch fresh DNS records, resolving these issues.

How to Access chrome://net-internals/#dns

1. Open Google Chrome.

2. Type chrome://net-internals/#dns into the address bar and press Enter.

3. You will land on the DNS internals page showing DNS cache details and actions available.

Step-by-Step Guide to Clear DNS Cache in Chrome

1. Open Google Chrome browser.

2. Enter chrome://net-internals/#dns in the address bar and press Enter.

3. On the page, locate and click the Clear host cache button. This clears all stored DNS entries in Chrome.

4. It is recommended to then visit chrome://net-internals/#sockets and click Flush socket pools to reset connection pools.

5. Restart Chrome for changes to take full effect.

This action removes cached DNS data, allowing Chrome to perform fresh DNS lookups the next time websites are accessed, potentially resolving browsing issues caused by stale DNS information.

Why and When to Clear DNS Cache

Clearing the DNS cache is useful when experiencing:

◾ Webpages failing to load or showing errors like DNS_PROBE_FINISHED_NXDOMAIN.

◾ Slow loading or unexpected redirections to wrong sites.

◾ Changes to DNS server settings or website IP addresses that are not reflected while browsing.

◾ Diagnosing network connectivity issues linked to DNS resolution.

It is a safe troubleshooting step to ensure Chrome’s DNS records are up to date.

Alternative Methods to Clear DNS Cache

In newer versions of Chrome, chrome://net-internals/#dns may be deprecated or not function reliably. Alternative system-level methods include:

◾ On Windows: Open Command Prompt as administrator and run ipconfig /flushdns.

◾ On macOS: Open Terminal and run sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder.

These commands clear the operating system DNS cache, which complements clearing the browser cache.

Common DNS Issues Addressed by Clearing Cache

* DNS lookup failures leading to inability to reach websites.

* Erroneous cached entries causing redirect loops or loading wrong pages.

* Network latency due to DNS requests clogging when cached entries are corrupted.

* Resolving DNS client service related issues on Windows or misconfigured DNS servers.

Conclusion

The chrome://net-internals/#dns tool in Google Chrome remains a valuable resource for diagnosing and clearing the browser’s DNS cache, helping resolve connectivity and browsing speed issues related to DNS. While some parts are deprecated in newer versions, clearing the DNS cache either via this tool or through system commands remains an effective troubleshooting step for DNS problems. Leveraging such tools can significantly improve web browsing reliability and responsiveness.

Follow-Up Questions

Q: What happens after clearing DNS cache in Chrome?
A: Chrome forgets all stored domain-to-IP mappings and fetches fresh DNS data for websites, which may cause a slight delay on the first load but usually resolves connectivity issues.

Q: Can I clear DNS cache on Chrome mobile?
A: Chrome mobile does not support chrome://net-internals/#dns, but clearing browsing data including cached files and cookies from settings can help clear DNS cache.

Q: Is it safe to clear the DNS cache regularly?
A: Yes, it is safe though usually unnecessary unless troubleshooting DNS-related issues.

Q: Why is chrome://net-internals/#dns sometimes not working?

A: Google has deprecated parts of the net-internals page in recent Chrome releases; system-level DNS flush commands are recommended alternatives.

Q: What is the purpose of chrome://net-internals in Google Chrome?

A:  The chrome://net-internals page is a built-in diagnostic tool that allows users and developers to monitor Chrome’s network activity in real time. It helps track HTTP requests, DNS resolutions, SSL handshakes, and proxy configurations.

Essentially, it’s used to debug connectivity problems, analyze performance issues, and log network traffic for further inspection.

Q: Why is chrome://net-internals deprecated, and what replaced it in newer Chrome versions?

A: Google has deprecated chrome://net-internals in newer versions of Chrome (from v100+ onward) because it was primarily a developer-level tool with a complex interface.

It has been replaced by the Chrome Net Export and Chrome://network tools, which provide similar functionality with a simplified UI.

You can now use:

◾ Chrome://network for viewing live network data.

◾ Chrome://net-export to record and save network logs.

Q: Can Chrome Net Internals help fix DNS or proxy-related connection problems?

A: Yes. Chrome Net Internals can help you identify and resolve DNS or proxy configuration problems.

◾ In the DNS tab, you can clear host cache to fix outdated or incorrect DNS entries.

◾ In the Proxy tab, you can check if your system proxy settings are interfering with Chrome’s network requests.

By analyzing logs and resetting DNS settings, many common connectivity issues like “DNS_PROBE_FINISHED_NXDOMAIN” can be resolved.
