The Domain Name System (DNS) works like the internet’s very own address book. It takes the easy-to-remember names we use, like “example.com,” and translates them into numerical IP addresses that computers understand to load websites. For speed, your browser stores (or caches) these DNS records locally. But here’s the kicker: those cached records can sometimes go stale or get corrupted, making it tough—or downright impossible—to access certain websites.
So, what’s the fix? Clearing your DNS cache! This nifty trick forces your browser to fetch fresh, up-to-date DNS records. It’s a quick and simple way to fix loading errors caused by outdated data. Stick around, and I’ll walk you through how to clear the DNS cache in all the big-name browsers, like Chrome, Firefox, Safari, and even on mobile devices.

What’s DNS Caching, Anyway?
Every time you visit a website, your browser has to figure out its IP address. Without caching, this would happen every single time you visited a new site—pretty slow, right? DNS caching speeds things up by saving these lookups on your device.
But here’s the rub: websites change! Maybe the site’s owner switched to a new server with a shiny new IP address. If your browser keeps clinging to that old cached data, you’ll hit snags like websites not loading properly or showing outdated pages. Clearing the cache wipes the slate clean so your browser can fetch the latest info.
How to Clear the DNS Cache in Popular Browsers
Chrome
Chrome doesn’t exactly make clearing the DNS cache a one-click affair, but don’t worry—it’s not rocket science either. Here’s what to do:
- Type
chrome://net-internals/#dnsinto the address bar and hit Enter. - Look for the “Clear host cache” button and give it a click.
- Now, restart Chrome to seal the deal.
- While you’re at it, clear out cached connections by typing
chrome://net-internals/#socketsinto the address bar. - Click “Flush socket pools” and restart Chrome one more time. Voilà, fresh DNS records!
Firefox
Good news for Firefox users: the DNS cache clears automatically every time you restart the browser. But if you’re feeling impatient, here’s how to do it manually:
- Pop “about:networking#dns” into the address bar and press Enter.
- Hit the “Clear DNS Cache” button, and you’re good to go!
Safari
For Safari fans, clearing DNS is as easy as flipping on the Developer menu:
- Go to Safari > Preferences, and under the Advanced tab, check “Show Develop menu.”
- Once that’s done, click Develop > Empty Caches, and boom—your DNS cache is gone.
Opera
Opera’s process is nearly identical to Chrome’s:
- Open
opera://net-internals/#dnsin the address bar. - Click “Clear host cache.”
- Next, type
opera://net-internals/#socketsin the bar. - Click “Flush socket pools,” and restart Opera for good measure.
On Mobile Devices
- iPhone: Toggle Airplane mode on and off or restart your device to flush the DNS cache.
- Android: If you’re using Chrome or Firefox, just follow the steps for their desktop versions. Easy-peasy!
