What is Google DNS?

Google DNS is mainly the specific address of a cache server of the search engine Google. Usually, when we visit a site, our computer’s browser and local DNS Server hold the data cache of the visited site. As a result, if we make any changes to our websites, it is not possible to see the changes immediately due to the previous cache held by the server. However, if you clean the cash, you can see the site in a normal way. In this case, we can clear our browser cache immediately, but it takes time to clear the cache that is in our local DNS server. But, you can solve this issue using Google DNS. Google’s default DNS is and

When we search for a website to visit, typing the URL in a browser, and if there is any cache of that website in the browser we can see the website from there. And if the cache of the browser is cleared, then the browser sends a request to a local DNS server and if there is any cache in the local DNS server, we can see the website from there. As a result, any changes to the website are not immediately visible to us. In that case, if we use Google DNS, the request from the browser goes to the Google DNS server instead of the local DNS server. And Google’s cache server is always updated very quickly. In that case, if we make any changes to the website, we can see the changes because of Google DNS.
