Have you ever opened a website and it didn’t load correctly? Or maybe the page showed an error even though your internet is fine? Sometimes, your browser stores wrong or old data that causes these issues. This is where clearing the DNS cache in Chrome can help.
Let’s learn what DNS is, why clearing the DNS cache is useful, and how you can do it in just a few steps.
What is DNS Cache? (In Simple Words)
DNS stands for Domain Name System. Think of it like a contact list for the internet. When you type a website name like www.google.com, your computer asks a DNS server to find the correct address (called an IP address) to open that website.
To save time, your browser stores this address for a while. This saved information is called DNS Cache.
But sometimes, this saved data becomes wrong or old.
For example:
- The website changes its server.
- You move to a new internet connection.
- The site updates its settings.
So your browser still tries to use the old address, and the page doesn’t open properly.
Why Should You Clear the DNS Cache?
Here are a few reasons to flush (clear) the DNS cache:
- Fix website loading problems
- Improve privacy
- Remove old or broken entries
- Update to the latest site info faster
How to Clear DNS Cache in Google Chrome
Chrome has a special internal page to manage DNS. Follow these easy steps:

Step 2: Clear the DNS Cache
You’ll now see a page with the title “Host resolver cache”.

Done! You’ve successfully cleared the DNS cache in Chrome.
BONUS: Clear Operating System DNS Cache (Optional)
Even though you cleared the Chrome DNS cache, your computer’s system also stores its own DNS cache.
Here’s how to clear that too:
For Windows
- Click on the Start button and type cmd.
- Right-click Command Prompt and choose Run as administrator.
- Type this command:
ipconfig /flushdns
- Press Enter.
- You’ll see a message:
- “Successfully flushed the DNS Resolver Cache.

- Open the Terminal app (search for it using Spotlight Cmd + Space).
- Type this command:
- sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
- Press Enter.
- Enter your password if asked.
There won’t be a success message, but it works silently.
Tips After Clearing DNS Cache

- Clear your browser cache too if problems continue:
