What is DNS Cache?

The DNS cache is a temporary database that houses information regarding previously visited websites. Whenever a user visits a website on any browser, the browser stores the DNS information in the cache for further use. 

This process helps the browsers speed up the webpage opening process for subsequent visits. Whenever a user tries to visit the same website again, the browser fetches the DNS information from the cache instead of looking it up again from servers. 

The Need to Flush DNS Cache

You may have noticed, at times, there are issues with browsing the internet and websites are not opening or taking too much time. It is because DNS gets corrupted or outdated. 

There is another possibility of websites changing their IP address and Chrome still has the old information. In all these cases, you need to flush the DNS cache to store new and updated DNS information.
