How to Perform DNS Cache Cleanup in Windows

If you can not reach your web site or view the current state, you may be having DNS problems.

DNS is automatically given to clients by the internet service provider, which is responsible for partitioning the Internet, naming partitions, and communicating sections. In some cases, however, the DNS address can be retrieved on demand.

Each unit that makes up the Internet network only has its own IP address. These IP addresses are reduced for easy-to-remember addresses such as for use by users. DNS servers keep the IP addresses of internet addresses registered.

When a client (computer) connects to the internete, it keeps the DNS address it receives from the internet service provider. For this DNS address you have given to your memory, you will not be asked for the DNS address again from the service provider. Sometimes the DNS server addresses in this memory lose their validity or they can change the DNS address of the relevant website. Although DNS problems may have improved in different ways, the problem of accessing a website in general is either caused by the loss of validity of the DNS address that the computer has previously received, or because of the change of the DNS address of the website to be connected.

You may not open websites at all if the DNS address has changed or lost its validity, or you may not be able to view the current state even if it is opened. To solve this problem you need to clear the dns cache. After DNS cleanup, your computer’s DNS memory will be deleted and you will receive a new IP address.

  • 1- From your computer, click Start> Run and follow the on-screen prompt. (You can use Start + R key combination)



  • 2. Write each command on the incoming call screen by typing the following commands in order, then press the enter key on your keyboard.

ipconfig / renew


  • After this process, you will successfully clear the DNS cache. We recommend that you check your access by restarting your Web browser.
