However, In Microsoft Windows 10, flushing the DNS resolver cache will help solve DNS related problems. Issues may involve unfinding errors on the website or not being able to access those evolving web pages.
What is DNS?
DNS means Domain Name System. It converts the names of websites into IP addresses that the computers can understand. For any website you wish to visit, this happens. Whenever a user visits a website by their hostname, the web browser initiates an internet search, but this search can not be fulfilled before the name of the website is “converted” to an IP address.
Meanwhile, Windows comes with an option that stores the specified DNS server address to speed up your browsing experience. The TCP / IP stack uses that IP address and refers to this user-specific DNS service or gateway-specific service to resolve the domain name of the website to its IP address and upload it to your web browser.

What is DNS Cache?
DNS cache refers to the temporary storage on a machine’s OS or web browser of information about previous DNS lookups. Holding a local copy of a DNS lookup helps your OS or browser to easily retrieve it and therefore the URL of a website can be much more conveniently resolved to its corresponding IP. The fundamental function of various types of caches is all more or less the same.
Not only does DNS caching happen at the OS and device level. In fact, a DNS lookup involves various steps as described above. The search passes through the resolver, root server, and TLD server in the process of a new DNS lookup. Information is collected at each stage and stored for later use. Therefore, even if the local DNS cache is empty, a cached copy of the necessary information may be accessible to the resolver, thereby avoiding the need to go through the entire DNS lookup phase.
How to View your Current DNS Cache
To view your current DNS cache, run Command Prompt as administrator and type ipconfig /displaydns. The command will produce a very long output.
