Clear DNS Cache – Speed ​​Up Internet

Flush DNS Cache – Speed ​​Up Internet : If you are having connectivity issues while browsing the internet, or if your internet speed is slow, it is a good idea to flush your computer’s DNS cache, which is quite simple and does not require any specific computer skills.

What is DNS?

The DNS (Domain Name System) cache is a central Windows system file that contains the hostnames and IP addresses of the websites you visit translated into a computer language, displaying the website name 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 DNS cache, which means you store information called resource records of all the websites you visit, making it easier to DNS lookups. To make 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 sluggishly, very slowly or not loading at all on a computer or laptop running Windows, it means that the DNS cache database is corrupted or the address Website IP has changed in the meantime, which can significantly slow down the network connection. Fortunately, in the event of an error, there is an easy way to update your DNS cache. Let’s do the following:

Clear DNS cache in Windows 11:

First step:

It is recommended to first delete the data stored in the browser you are using. In the Chrome browser (the others are similar), right-click on the three dots in the upper right corner, and select Settings from the drop-down menu, then select Privacy and security from the new menu on the left. A new window has appeared where you can delete stored browsing data and cookies by clicking on the Clear browsing data entry.

Second step:

Simultaneously press the Windows -Logo + R keys on the keyboard and in the Run window that appears, type the following command in the search field, then press the Enter key or click the OK button:

  1. ipconfig /flushdns
in the Run window, type ipconfig /flushdns

Warning: After ipconfig, before the sign / (slash) there is a space.

Comment:

Because the file is not a long entry, the deletion only takes a second, which consists of a code snippet running at a discrete speed, then the command line exits immediately.

The operation deletes all stored information. At first, you may find that websites take longer than expected to open, but your computer caches new, more relevant information and the internet connection speed improves.

Why Flush DNS Cache on Windows 11?

There are two other important reasons for doing this, namely that the DNS cache needs to be flushed from time to time.

The first reason is the protection of personal data:

Unlike the 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 gain access to 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 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. credit.
