The DNS cache saves recent DNS lookup results. It’s stored on a user’s computer or device5. When someone asks for a website, their browser first looks in the DNS cache for the site’s IP address4. If the info is there, the browser can go straight to the site. This skips the need to look up the site’s DNS again, which saves time4.

Overall, tending to the DNS cache keeps the internet safer and works better. Knowing the good reasons to clear the DNS cache can make your web browsing not only faster but also safer from online dangers345.
