Are you trying to flush the DNS on Windows 10? You’re not the only one. Modern computers are convenient because they keep a record (sort of) of the websites you visit in the DNS cache.
This information is not permanent. The files eventually expire, prompting the system to remove them. But that raises a question. If your PC eliminates these files after a given period, why would you bother emptying the cache yourself?
How To Flush DNS Windows 10?
Don’t bother looking for the DNS in your computer’s storage. You will find it in the system memory. Interestingly enough, you lose the contents of the system memory whenever you shut the PC down.
This tells you why restarting a computer fixes common computer problems. You can flush the DNS cache manually without restarting the computer. You don’t have to wait for a technical problem to occur to take this step.

Flushing the DNS improves your security. Do you hate the idea of intruders seeing your internet activity? Flushing the DNS will eliminate the record of addresses you’ve visited.
Factors such as page validity can tell people volumes about you and your personal life. If you have nothing to hide, flushing is still important because it protects you from hackers.
If they access the cache, they can change the entries, which doesn’t sound so bad until you realize that a poisoned DNS cache can easily lead you to fake websites where scammers can steal your money and personal information.
Run Commands to Flush DNS on Windows 10/11
Therefore, you shouldn’t underestimate the important role DNS flushing plays. The process involves the following:
1. Use Windows and ‘R’ to access the ‘Run’ dialog box.
2. You can reach the command line via the ‘Run’ dialog box by typing ‘CMD.’

3. Type ‘ipconfig/flushdns.’

If you succeed, the system will send you a message revealing that you cleared the DNS resolution cache.
The process is as straightforward as they come. As you can see, it only takes three steps to accomplish the task. Again, you don’t have to wait for problems to occur to flush the DNS.
What is DNS Cache?
What purpose does it serve? Do you even need to flush the DNS? These questions are impossible to answer for people who don’t even know what the DNS cache is, let alone what it does.
Do you know how your computer connects you to a website? Yes, you start by typing the address in the box. But the computer doesn’t know what those words mean.
This is where the Domain Network System enters the picture. It turns the web address into an IP address. The computer can use that IP address to find the website you want.
But this doesn’t happen every time. Whenever you visit an online platform, the computer takes the information acquired from the DNS server and keeps the data in the DNS cache.
The goal is to reduce the time it takes to access a website. The system uses the information in the DNS cache to resolve the domain name into an IP address whenever you type the web address into the address bar.
Again, the data in the DNS cache is temporary. Think of it as a list of domains you have visited in the past. But the DNS cache is not perfect. It is susceptible to corruption, creating unexpected glitches.
The same problems can occur if the cache is out of date. For instance, what happens when the IP address of a website you visited in the past changes? What if someone poisons the cache with the wrong information, either intentionally or with malicious intent?
Once the DNS cache is poisoned, corrupted, or outdated, your online activities will suffer. You may find that it is difficult, if not impossible, to open certain websites.
Admittedly, this can occur because of other issues. But if you consult an IT expert because you can’t access a particular website, they will encourage you to start by flushing the DNS cache. If this doesn’t solve the problem, they will inspect the various hardware and software components of your computer. However, in many cases, flushing the DNS solves the problem.
