Chrome Net Internals DNS Tool

The internet sometimes feels slower than it should. A website doesn’t load or takes you to the wrong place. If this sounds familiar, the problem may not be with the site or your internet—it could be your DNS cache. Fortunately, Chrome Net Internals DNS is a powerful but frequently overlooked feature. We’ll explain what this tool is, why it’s important, how to use it, and when you should clear your DNS cache in this guide. In 2025, we will also respond to frequently asked questions.

What Is DNS and Why Is It Important?

The Internet’s address book is referred to as the DNS, or Domain Name System. DNS converts a website like example.com into an IP address that can be read by computers, like 192.0.2.1. That IP address is what your browser uses to connect to the website.

To save time and speed up your internet experience, Chrome (and your operating system) temporarily stores Chrome Net Internals DNS entries in something called the DNS cache. But when this cache becomes outdated or corrupted, it can lead to errors like:

Sites are not loading properly
Redirects to incorrect servers
Slow loading speeds

That’s where the Chrome Net Internals DNS tool becomes useful—it gives you control over Chrome’s DNS cache.

What Is Chrome Net Internals DNS?

Google Chrome includes a diagnostic tool called Chrome Net Internals DNS. It lets you see, look at, and clear the DNS cache in the browser. It is built into Chrome and does not require any extensions or command-line tools.

To access it:

Open a new Chrome tab.
Type chrome://net-internals/#dns in the address bar.
Press Enter.

You’ll be taken to a detailed DNS page showing cached domain entries and options to clear them.

This tool is helpful when DNS issues affect only Chrome and not the entire system, which happens more often than you’d think.

When Should You Use Chrome Net Internals DNS?

There are several cases where this tool can save you time and trouble:

1. After DNS changes

If you’ve changed DNS settings (e.g., switched to Google DNS or Cloudflare DNS), Chrome might still be using old cached entries. Clearing them ensures Chrome uses the latest configuration.

2. After website migration

If a website has changed servers or IP addresses, Chrome may still try to connect to the old one. This causes errors or outdated pages to load. Using Chrome Net Internals DNS clears this issue instantly.

3. When a specific site won’t load

If one website repeatedly fails to load while others work fine, your DNS cache might be corrupted. Flushing Chrome’s DNS cache could fix the problem immediately.

How Do You Use Chrome Net Internals DNS to Clear DNS Cache?

Follow these simple steps:

Open Chrome.
In the address bar, type:
chrome://net-internals/#dns
Press Enter.
You’ll see two main sections:
- Host resolver cache
- Clear host cache button
Click Clear host cache.

That’s it! Your DNS cache is cleared, and Chrome will now fetch fresh DNS information from your current provider.

Pro Tip: Refresh your tabs after clearing the cache to reload DNS data for those sites.

Does It Affect the Entire Computer or Just Chrome?

Good question. Clearing DNS through Chrome Net Internals DNS only impacts the browser, not your operating system or other applications.

If you want to clear the system-wide DNS cache, you’ll need to use command-line tools:

Windows:
Open Command Prompt and type:
ipconfig /flushdns
macOS:
Open Terminal and type:
sudo killall -HUP mDNSResponder
Linux:
Depending on your distribution, use:
sudo systemd-resolve–flush-caches

So, Chrome’s tool is ideal for browser-specific DNS issues. If you’re experiencing problems across all browsers, clear your system cache too.

Is It Safe to Use Chrome Net Internals DNS?

Absolutely. This tool doesn’t delete your browsing history, cookies, saved passwords, or settings. It only clears cached DNS data stored temporarily by Chrome.

This makes it a safe and effective way to resolve website access problems or loading errors.
