When browsing the internet, you might occasionally encounter issues like websites not loading or showing errors such as “DNS_PROBE_FINISHED_NXDOMAIN.” While these problems often seem complex, most of the time, the issue lies in your DNS cache. Fortunately, Google Chrome includes a hidden but powerful tool called chrome.//net-internals/dns history, which allows you to view, analyze, and clear DNS data directly within the browser.
In this article, we’ll explore what chrome.//net-internals/dns history page is, how it works, and how you can use it to fix common DNS-related problems in Chrome without relying on third-party tools.
What Is chrome.//net-internals/dns History?
The chrome.//net-internals/dns history page is a diagnostic utility built into Google Chrome that helps users monitor and troubleshoot network activity. This secret page shows detailed DNS (Domain Name System) logs — the information Chrome stores when you visit websites.
Every time you type a web address like www.google.com, Chrome converts it into an IP address through a DNS lookup. These DNS results are stored temporarily in Chrome’s internal cache to make your future visits faster. However, over time, outdated or corrupted entries can cause connection issues, making it essential to manage and occasionally clear them using this tool.
Why You Should Use chrome.//net-internals/dns History
Most users never realize how valuable the chrome.//net-internals/dns history page can be. Whether you’re an IT professional or just a regular user, this feature allows you to:
- View all cached DNS entries currently stored in Chrome
- Identify potential DNS errors or failed lookups
- Monitor network performance and domain resolutions
- Clear outdated DNS records that may be causing website loading issues
By regularly checking and clearing your chrome.//net-internals/dns history, you can maintain smoother browsing performance and minimize DNS-related errors.
How to Access the chrome.//net-internals/dns History Page
Accessing this hidden page is straightforward. Follow these steps:
- Open your Google Chrome browser.
- In the address bar, type chrome.//net-internals/dns history and press Enter.
- You’ll see a page displaying a detailed list of active and expired DNS entries.
You can analyze how Chrome has resolved various domains, including timestamps and IP addresses. However, the most useful feature for many users lies in the chrome //net-internals/#dns clear command — which allows you to delete all cached DNS data.
Using chrome //net-internals/#dns clear to Fix DNS Errors
If websites are not loading correctly or show repeated DNS errors, the best first step is to clear your DNS cache in Chrome. Here’s how:
- Open Chrome and type chrome //net-internals/#dns clear into the address bar.
- Press Enter, and you’ll see a button labeled “Clear host cache.”
- Click it to remove all stored DNS records instantly.
After clearing the cache, restart your browser and try revisiting the problematic site. In most cases, this simple fix resolves issues like slow loading or “site not found” errors.
By running chrome //net-internals/#dns clear, you essentially reset Chrome’s memory of domain lookups. This ensures your browser performs fresh DNS requests, reducing the likelihood of connection failures caused by outdated records.
Advanced Tips for Managing DNS in Chrome
If you’re frequently dealing with network interruptions or website errors, you can combine chrome.//net-internals/dns history tools with system-level DNS commands.
Here’s what you can do:
- Flush System DNS Cache (Windows):
Open Command Prompt and type:
ipconfig /flushdns
This clears the entire system-wide DNS cache, complementing what you’ve already done in Chrome. - Restart Chrome’s DNS Resolver:
After clearing using chrome //net-internals/#dns clear, close all Chrome tabs and relaunch the browser. This ensures all DNS processes restart properly. - Use Public DNS Servers:
Switch to reliable servers like Google DNS (8.8.8.8 / 8.8.4.4) or Cloudflare DNS (1.1.1.1) for faster and more consistent name resolution.
These methods, along with periodic clearing using chrome //net-internals/#dns clear, help keep your network clean, stable, and optimized.
