Windows users will need to open Command Prompt from the Start menu. To clear DNS cache, issue the following command once you are inside the prompt. It works by translating domain names you enter in your browser’s search box with the IP address to allow your browser to reach the webserver and retrieve its contents.
Another way DNS resolution works is from IP to domain. For this, your browser/OS will send name resolution queries to DNS servers as per your system’s/browser’s/ISP’s configuration. There are many places that you can choose which DNS resolvers or name servers to use. One may be more important than the other. Your VPN service could override the DNS server set up by your ISP.
Because DNS queries can take some time to process, your browser and operating system may store DNS query results in cache. Although this cache can improve response time, you might need to clear it as it could become obsolete. Old caches can also pose privacy and security concerns, as they may be used to track user activity. Clearing browser cache might not remove DNS cache from all locations. Knowing the exact process will help.
This article will cover simple steps you can take to clear your DNS cache and other browsers.
