How to Use Chrome Net Internals DNS Tool to Flush Cache in 2025

If websites won't load, browsing is slow, or you're getting the wrong page redirect, there's a high probability that your DNS cache in your browser is to blame. The best part? Google Chrome includes a super handy tool to flush out your DNS cache — and it's named Chrome Net Internals DNS.

In this entire 2025 tutorial, we will take you through all that you must know regarding how to utilize Chrome Net Internals DNS to clear cache and resolve connectivity issues quickly and securely.

What is Chrome Net Internals DNS?

It is useful to know what Chrome Net Internals DNS is before jumping into the how-to guide.

Chrome Net Internals DNS is an in-built diagnostic page for Chrome that allows you to observe and control the way the browser processes domain name system (DNS) queries. It includes functionality for examining DNS lookup history, troubleshooting errors, and most helpful of all, clearing the DNS cache straight from your browser.

This comes in handy, particularly in 2025, where users often hop between VPNs, proxy servers, and dynamic networks — all of which can disrupt domain name resolution.

Why Clear DNS Cache?

The DNS cache is a bank of visited domain names. When you browse to a site, Chrome caches the DNS to ensure future visits are quick. Occasionally, however, this cache becomes outdated or compromised.

Some typical reasons to clear the cache using the Chrome Network Internals DNS tool are as follows:

• Website not loading correctly

• Page redirects to incorrect URL

• Receiving regular DNS-related error messages

• Network switching (e.g., from office to home Wi-Fi)

• Alterations made to your DNS server or settings

Clearing the cache resets all DNS records in Chrome and makes it reload fresh ones, usually solving the issue immediately.

Step-by-Step: How to Clear DNS Cache Using Chrome Net Internals DNS (2025 Update)

Here’s the simple process to flush the DNS cache using the Chrome Network Internals DNS tool:

Step 1: Open Chrome Net Internals DNS

Launch Google Chrome.

In the address bar, type:

bash

Copy

Edit

chrome://net-internals/#dns

Press Enter. You’ll be taken to the Chrome Net Internals DNS dashboard.

Tip: This interface is entirely secure and part of your browser. You won't have to worry about downloading any third-party apps or extensions.

Step 2: Inspect Current DNS Records

Here, you can view all the DNS hostnames Chrome has resolved, along with their expiration times and resolved IP addresses. The information provides an overview of Chrome's internal DNS usage.

If you’re troubleshooting a specific website, this view can help identify whether the domain has an outdated or mismatched DNS entry.

Step 3: Click "Clear host cache."

This is the magic button.

Locate the "Clear host cache" button (usually found right at the top).

Click it once.

Chrome will immediately flush its DNS cache. This clears out all cached domain name data and allows the browser to make new DNS queries from scratch.

That’s it! You’ve just used the Chrome Network Internals DNS tool to clear your cache.

Bonus: Restarting Sockets (Optional)

Some users find it helpful to also flush active socket pools after clearing the DNS cache.

Here’s how to do it:

In the address bar, type:

bash

Copy

Edit

chrome://net-internals/#sockets

Press Enter.

Click "Flush socket pools".

This ensures that any lingering network connections are refreshed, which is especially useful if you’re still seeing DNS-related issues after clearing the cache.

When To Use Chrome Net Internals DNS?

Although you don't have to flush the DNS cache daily, there are certain scenarios in which it can be extremely useful:

• After modifying your DNS server (for example, to Google DNS or Cloudflare)

• When a site that used to load completely just refuses to load

• After swapping website hosts (for web admins and developers)

• When using VPNs or proxies that cloak domain origins

• When troubleshooting browsers for sluggish or unstable network performance

With the help of the Chrome Network Internals DNS tool, you don't have to be technical to take these actions. Anyone can accomplish it within 30 seconds or less.
