Flush DNS cache - Speedup internet
If you're experiencing connectivity issues while browsing the Internet, or your Internet speed may be slow, it's a good idea to flush the DNS cache on your computer, which is fairly straightforward and requires no special computer skills.
Quick Tip: You can clear your DNS cache on Windows 11 in just 1-2 minutes to improve the speed and performance of your Internet connection.
What is a DNS cache?
The DNS Cache (Domain Name System) is a Windows central system file that contains the host names and IP addresses of the websites you visit translated into a computer language, displaying the name of the website in numbers that the system can read (eg 192,555). 438.12).
Like web browsers, operating systems store previous Domain Name System (DNS) lookups in a so-called DNS cache, which means that you store pieces of information called Resource Records from all the websites you visit, which simplifies DNS lookups. So that web pages load faster the next time you visit the same IP address (the same web page).
If you find that your favorite website is loading stagnantly, very slowly, or does not load at all on a computer or laptop running Windows, it means that the DNS cache database is corrupted or that the website's IP address has changed in the meantime, which can significantly slow it down the network connection. Fortunately, in the event of an error, there is an easy way to update your DNS cache. Do the following:
Clear the DNS cache on Windows 11:
First it is recommended to delete the data stored in the browser you are using. In the Chrome browser (the others are similar), right-click the three dots in the top right corner and select Settings from the drop-down menu, then select Privacy and Security in the new menu on the left. A new window has appeared where you can delete the stored browsing and cookie data by clicking on the Delete Browsing Data entry.
Simultaneously press the Windows -Logo + R keys on the keyboard and in the Run window that appears, type the following command in the search box, and then press the Enter key or click OK:
- ipconfig /flushdns
Attention!: After ipconfig, (before the / (forward slash) sign, is a space.
Because the file not a long entry, deleting takes only a single second, which consists of a snippet of code running at an unobtrusive speed, then the command line closes immediately.
The operation removes all stored information. At first, you may find that it takes longer than expected to open Web sites, but your computer caches new, more relevant information, and your Internet connection speed improves.
Why clear the DNS cache on Windows 11?
There are two other important reasons to perform this operation, for which is that the DNS cache needs to be emptied from time to time.
First reason is the protection of personal data:
Unlike cookies used by browsers, the information stored in the cache contains much less information about the websites you visit, however, if someone accesses the DNS cache, your privacy may be compromised.
The second reason is basic security:
If hackers and cybercriminals access the DNS cache, they can change the IP addresses of websites hosted there and even insert new ones. This is called DNS poisoning and can be quite a security issue as they can be redirected to another site where they can collect our confidential information, such as account passwords and credit card information.
