Had concerns with DNS resolution? Do you need to clear the DNS cache on your Windows 10 device or server? Then you are most welcome. In this guide, you are going to learn how to clear or flush DNS cache in Windows in 3 Different ways.

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 is the “Domain Name System.” It translates website names into IP addresses that can be interpreted by computers. This applies to every website you choose to visit. The web browser initiates an internet search if a user visits a website by its hostname, but this search cannot be done until the website name is “converted” to an IP address.

In the meantime, Windows comes with the option that stores the required DNS server address to speed up your browsing experience. The TCP/IP stack uses the IP address and refers to this user-specific DNS service or gateway-specific service to download the domain name of the website to its IP address and upload it to the web browser.

What is DNS Cache?

DNS Cache refers to the temporary storing of information about previous DNS lookups on a machine’s OS or web server. Holding a local copy of a DNS lookup allows it easier for your OS or browser to retrieve it, meaning a web site’s URL can be resolved to the corresponding IP even more conveniently. The basic function is more or less the same with different kinds of caches.

DNS caching not only happens at the level of the OS and system. In fact, as mentioned above, a DNS lookup implies different steps. In the course of a new DNS lookup, the search passes through the resolver, root node, and TLD server. At each point, information is gathered and processed for later use. Therefore, even if the local DNS cache is empty, it might be possible to access a cached copy of the required information.
