In this video, we’ll show you a handy macOS Big Sur terminal command that can help you fix a common issue with your computer’s DNS (Domain Name System). If you’re frequently seeing 404 errors or web pages not loading, it might be because your DNS is acting up. But don’t worry, this command can help you flush and reset your DNS, and get your internet back up and running in no time!
Just a heads up, while Terminal commands are commonly used by IT folks, if you’re not a pro at typing them, don’t worry! On an Apple Mac, simply rebooting the computer will automatically clear its DNS Cache.
Note: DNS (Domain Name System) is like a digital Yellow Pages, but instead of matching names and addresses to phone numbers, it helps us convert IP addresses to domain names and vice versa.
However in order to speed up page loading when browsing the internet. After visiting a website, that sites address is stored locally on your computer in something called a “Cache“. This cache is then referred to when you try and revisit the same page, which makes loading that page faster.
> say DNS cache has been flushed
You’ll startle a lot of people with this 😀
