How Do I Flush My DNS Cache on Windows?

The following guide will teach you how to flush your DNS Cache.

The first step to flushing your DNS is to open your “Windows Command” prompt.

WinXP: Start, Run and then type “cmd” and press Enter.
Vista, Window 7 and Windows 8: Click “Start” and type the word “Command” in the Start search field. Finally, right-click the command prompt icon and select the option to “Run as Administrator”.
In the open prompt, type “ipconfig /flushdns” (without the quotes).
You should receive a message of your success as confirmation when the cache is cleared.

Adding Google DNS To Your PC / Laptop

The first advantage to using Google Public DNS is speed, reliability and performance.

Google already crawls the internet regularly and part of the process is to resolve and cache all DNS information. Because of this they are able to support high-volume searches because a big portion of their answers are coming from their cache. This decreases the time needed to answer a query since generally speaking they already have the answer. This also provides more reliability and increased performance, faster query times mean pages load faster and there is less down time. Your ISP can have less stable servers which cause a website to fail to load or load very slowly.

The second advantage to using Google Public DNS is security.

Google Public DNS fully supports DNSSEC or Domain Name Security Extensions which works agains cache poisoning attacks. Cache poisoning is essentially an attempt to redirect users from their intended destination to a malicious site. Sometimes cyber criminals can even take control of an entire DNS zone. With Google Public DNS you get extra security agains these types of attacks. Google Public DNS also offers DNS-over-HTTPS, or DNS resolution over top of and HTTPS connection, which is yet another level of security that prevents eavesdropping, tampering or spoofing.

The last thing to mention is correctness. Google will always return the exact answer to your query, even if you have mistyped or misspelled something. Some ISPs will redirect you and change the direction you are trying to go, and Google won’t.

Google always wants new ways to enhance your browsing experience and provide you with a valuable service. Google Public DNS is a tool to that you can use to hopefully increase the quality of time you spend online.
