Command Used: ipconfig /displaydns
In this tutorial, we will show you how to view the DNS cache contents in Windows 10. DNS cache refers to the temporary storage of information about previous DNS lookups on a machine’s OS or web browser.
A DNS (Domain Name System) resolver cache is a temporary database, maintained by Windows, that contains records of all your recent visits and attempted visits to websites and other Internet domains.
The Internet relies on the Domain Name System (DNS) to maintain an index of all public websites and their corresponding IP addresses. Every time a user visits a website by its name (such as "tenforums.com"), the user's web browser initiates a request out to the Internet, but this request cannot be completed until the website name is converted into an IP address.
This conversion process is called name resolution and is the job of DNS, but it takes time. A DNS cache attempts to speed up the process by handling the name resolution before the request is sent out to the Internet.
If the IP address of a website changes before your DNS cache updates, you may not be able to load the webpage. If you are running into a lot of Page Not Found errors and you know you are connected to the Internet, you could try flushing your DNS cache to have your computer request new information.
Windows stores a list of DNS cache entries that contain a list of the websites you visit with their remote server names and their corresponding IP addresses. You can view or export your DNS cache. Here's how.
