Understanding DNS Cache
What’s DNS cache? It’s a temporary database that stores information about the domain name system (DNS). When you visit a website, your device looks up the domain name and associates it with the website’s IP address. The DNS cache stores this information so your device can quickly access the site the next time you visit, without having to perform the lookup again. This improves internet speed and reduces the load on DNS servers. However, the cache can sometimes become outdated, leading to issues like slow loading or even website errors. That’s when you might need to clear the DNS cache to fix internet problems.
How Outdated DNS Cache Can Cause Internet Issues
When can outdated DNS cache cause internet issues? Outdated DNS cache can lead to frustrating internet problems. If your device has an outdated record of a website’s IP address, it can’t properly connect to that site. This can cause timeouts, broken links, and other glitches.
Outdated DNS cache is common if you’ve recently changed internet service providers or modified your network settings. To fix it, you’ll need to clear your DNS cache. This forces your device to look up the current IP address, restoring your internet connection. It’s a quick and easy way to troubleshoot many common network issues. Try clearing your DNS cache next time you encounter frustrating internet problems.
Clearing Your DNS Cache in 60 Seconds
Clearing your DNS cache takes only a minute and can quickly resolve many internet connectivity issues. First, open your computer’s command prompt or terminal.
On Windows, type “ipconfig /flushdns” and hit Enter.
On Mac or Linux, type “sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder“.
You’ll see a confirmation that your DNS cache has been cleared. This removes outdated information, forcing your device to look up the correct IP addresses when you visit websites.
After clearing the cache, try accessing the problematic website again. The cached data will be refreshed, potentially fixing any connectivity problems you were experiencing.
Clearing your DNS cache is an easy troubleshooting step that’s worth trying before moving on to more complex solutions.
Benefits of Clearing Your DNS Cache
Why is clearing your DNS cache so beneficial? When you clear your DNS cache, you can resolve website addresses faster. This improves your internet speed and performance.
