Clearing the DNS cache is good for security
But what is the dns cache? We can say that it is where all the domain searches you have made are stored. That is, simply by entering the RedesZone website or any other, a small record is created and stored. It is stored in Windows and what it does is translate the domain name, which would be redeszone.net, by the IP address that corresponds to the web. In this way you do not have to enter the IP to enter a page, something that would be difficult to memorize.
From then on, every time you go back to a page or search for something, the browser will access that DNS cache to obtain the IP. It’s a quick process and we don’t really realize it. By using previously stored data, the computer avoids having to request it again and saves time.
Now that DNS cache could be a danger. Why? It could become corrupted over time and a hacker could introduce fake DNS servers. This means that they could modify, for example, the DNS that you have stored from Facebook or Amazon. When you enter those pages, you will actually be automatically redirected to another one created by a cybercriminal who only seeks to steal your passwords or sneak in a virus. They could even be a carbon copy of the originals.
Thus, clearing the DNS cache can improve your security. It is especially useful if you suspect that what we mentioned may have happened. In addition, it could also help to improve certain problems with the connection.
What to do to clear the DNS cache in Windows
What steps must be taken to clear the DNS cache in Windows? It is very simple in both Windows 10 and Windows 11. What you have to do first is go to Start and enter the Symbol of the system. Once there you have to execute the following command to carry out this action:
ipconfig /flushdns
Simply with that, the DNS cache in Windows will be automatically flushed. Everything it had stored will be deleted and from there it will start saving all requests again. At any time you can run that command again and empty it again if necessary.
But your browser, how can it be Google Chrome, it could also store a DNS cache. Therefore, to complete what we mentioned, you should delete it anyway. It is also a simple process and it will not take you long to do it.
In the case of Chrome, the fastest way is to enter chrome://net-internals/#dns and click on Clear host cache. What you have stored in the browser will be automatically deleted.
In short, with this small change that you can make both in Windows and in the browser you use, you can improve your security. It is also useful if you have problems with the connection, for example a web page does not load. For example, it is useful for troubleshooting failures like DNS PROBE FINISHED NO INTERNET.
