Flush DNS to fix Internet connection issues

Technically speaking, DNS, or Domain Name Servers, are like a phone book of addresses. These servers keep a directory of domain names (websites you visit) and they convert these website domain names to IP (Internet Protocol) addresses. This conversion must happen so computers can access websites according to IP addresses. Most of the time though, your PC’s DNS is managed without any problems, but sometimes when you can’t access certain websites, emptying your DNS can solve these issues.

With the technical mumbo jumbo behind us, it is okay for you to perform this procedure on your PC running Windows 7, 8, 8.1 and 10. It’s an easy procedure to do and it can improve the stability of your Internet connection.

Let’s begin with Windows 7. Click the Start button, click “All Programs,” click “Accessories,” and then right-click “Command Prompt” and choose “Run as Administrator.” Click “Yes” to give it permission. Next, type in exactly, including any spaces and slashes, “ipconfig /flushdns” without the beginning and ending quotation marks. There is a space between the word “ipconfig” and the forward slash. Hit enter to run. When it is complete, you will see “Windows IP Configuration,” “Successfully flushed the DNS Resolver Cache.” Now, type in “exit” (without quotes) and hit enter, to close the window.

To flush the DNS in Windows 8 and 8.1, first be sure you are on the Start screen (with all the colored tiles) and move your cursor to the upper-right corner to expose the charm bar. Click “Search.” Type “cmd” (without quotes) in the search field. In the list that appears, right-click on “Command Prompt” and then click “Run as Administrator.” Click “Yes” to allow it to run. Next, in the window, type in exactly, including any spaces and slashes, “ipconfig /flushdns” without quotation marks. There is a space between the word “ipconfig” and the forward slash. Hit enter to run. When it is complete, you will see “Windows IP Configuration,” “Successfully flushed the DNS Resolver Cache.” Now, type in “exit” (without quotes) and hit enter, to close the window.

Windows 10 is similar to 8 and 8.1, but accessing the command prompt is a little different. First, click the Start button in the lower-left corner and then click “All apps.” Open the menu that displays all your applications. Scroll down and click the folder “Windows System.” Next, right-click “Command Prompt” and hover over “More,” and then click “Run as Administrator.” Click “Yes” to allow it to run.

Next, in the command prompt window, type in exactly, including any spaces and slashes, “ipconfig /flushdns” without quotation marks. There is a space between the word “ipconfig” and the forward slash. Hit enter to run. When it is complete, you will see “Windows IP Configuration, Successfully flushed the DNS Resolver Cache.” Now, type in “exit” (without quotes) and hit enter to close the window.

You can do this anytime you find difficulties with your Internet connection. It may also help resolve connection issues with certain websites. I found that this procedure did in fact help improve the reliability of my Internet connection and speed.
