How to Reset DNS Cache

In the world of internet, there are lots of things ongoing at every single moment. Since the starting, the internet has evolved quite a log despite the fact that we, the end-users, aren’t that much familiar with those. DNS is one of the main parts of the play that makes sure that you connect to the proper server instead of a wrong one.

DNS is a huge database service where all the websites and their respective IP addresses are stored. Whenever you type any website URL in your browser, it contacts with the DNS and retrieves the server’s IP address. Then, using the IP address, you get to enjoy all the great services – YouTube, Google, Facebook etc. You should switch to a faster DNS server for enjoying better internet quality.

In some cases, your browser may show DNS errors. The browser saves a copy of the DNS cache in its memory so that instead of asking the DNS server every single time, it can directly load the IP address from the memory, saving further time. However, caches are temporary files and can become corrupted in cases. The server’s address may also change time to time.

In such scenario, you have to refresh the DNS cache of your browser. Let’s take a look how to do it.
