DNS (Domain Name System) cache is a process or algorithm that Google Chrome and other browsers use to improve website loading time. When you visit a website, your browser has to translate the website address (like into an IP address that computers understand. This translation process from a website name to an IP address is a complex task that can take time. To make this process faster, browsers such as Google Chrome keep a local cache (a temporary storage) of these translations.

Google Chrome has built-in DNS cache tools for performance improvements like other browsers. Sometimes, the DNS entries conflict as you get the duplicate old DNS entries, so the clearing process is necessary. Due to its importance, Google Chrome lets you flush or clear the DNS cache on your browser. 

What Exactly is the DNS Cache?

DNS data is the entries of websites that you browse frequently. Browsers keep the DNS cache of websites to speed up the loading process. Also, if the ISP or DNS is offline, you can access that particular website through cache with the help of stored tiny cache data. When a website’s DNS entry changes, you need to update it in the browser to reach the correct website and IP address.
