How to Clear Cache in Chrome Browser?
By Kathir | July 11, 2026
In the realm of web browsing, speed and efficiency are paramount. Web browsers like Google Chrome are designed to provide users with a seamless experience, but occasionally, technical issues can hamper this experience. One such issue is the accumulation of outdated DNS (Domain Name System) information in the clear cache of browsers, which can lead to slow loading times and connectivity problems. In this article, we will delve into the details of Chrome’s DNS cache, and more importantly, how to clear or flush it using the chrome://net-internals/#dns tool.
Understanding DNS Cache and Its Importance:
Before diving into the specifics of chrome://net-internals/#dns, let’s take a moment to understand what DNS cache is and why it matters.
The DNS is like the internet’s phonebook, translating user-friendly domain names (e.g., www.example.com) into IP addresses that computers use to identify each other on the internet. To avoid repeatedly querying DNS servers for the same information, web browsers store this translated data in a cache. This cache speeds up subsequent visits to the same websites, as the browser doesn’t need to fetch DNS records again. However, over time, this cache can become cluttered with outdated information, leading to connectivity issues or delays in loading websites.
Introducing chrome://net-internals/#dns
Google Chrome, like most modern browsers, has a hidden tool known as “chrome://net-internals/#dns” that allows users to interact with various network-related functions, including DNS. This tool is primarily intended for developers and advanced users, but anyone can utilize it to clear or flush the DNS cache.
Clearing DNS Cache Using chrome://net-internals/#dns
Clearing the DNS cache using chrome://net-internals/#dns is a relatively simple process, but it’s important to note that this action can have consequences. For instance, after clearing the DNS cache, your browser will need to fetch DNS records again for all websites you visit, which might slightly delay loading times. Here’s how to do it:
Step 1: Open a New Tab:
In Google Chrome, open a new tab in your browser.
Step 2: Enter the URL:
In the address bar of the new tab, type “chrome://net-internals/#dns” (without quotes) and press Enter.
Step 3: Navigate to DNS:
In the “chrome://net-internals” page, you’ll find a menu on the left. Click on “DNS” to access the DNS cache management options.
Step 4: Clear Cache:
Under the “Host resolver cache” section, you’ll see a button labeled “Clear host cache.” Click on this button to clear the DNS cache.
Step 5: Confirmation:
A dialog box will appear, confirming the action. Click “Clear” to proceed.
Flushing the Entire DNS Cache:
While the above steps clear the host resolver cache, Chrome also offers an option to flush the entire DNS cache. Flushing the cache removes all cached DNS records, which can be useful if you’re experiencing widespread connectivity issues or if you suspect that the cache has been significantly compromised.
Step 1: Access the DNS Cache:
Follow steps 1 to 3 from the previous section to access the DNS management options.
Step 2: Flush Cache:
Under the “Internal DNS Cache” section, click on the “Clear host cache” button. This action will flush the entire DNS cache.
Step 3: Confirm Action:
A confirmation dialog will appear. Click “Clear” cache to proceed with flushing the DNS cache.
Benefits and Considerations:
1. Improved Performance:
Removing outdated DNS records ensures that your browser fetches accurate and up-to-date information, potentially improving loading times.
2. Resolve Connectivity Issues:
Clear cache can resolve problems related to DNS resolution, which might lead to difficulty accessing certain websites.
3. Testing and Development:
Developers often use chrome://net-internals/#dns to simulate DNS-related scenarios during testing and development. However, it’s essential to consider the following:
4. Temporary Delay:
Clear cache of DNS might cause a brief delay when accessing websites, as the browser needs to fetch DNS records again.
5. Privacy Implications:
Clear cache might also impact your privacy, as websites you visit might be able to track your behaviour more easily if their DNS records need to be fetched new.
