In this article, we’ll be covering simple steps that you can use to clear the DNS cache on your system and different browsers. Clearing the browser cache may not clear up the DNS cache at all places, so knowing the specific process will help. An old cache may also be an issue due to privacy and security reasons, as this may be used for tracking user activity. This cache is useful in improving response time though you may need to clear this cache as it may become outdated. Your operating system and browser may cache DNS query results for faster response time as there is some latency involved in querying from DNS servers. Like your VPN service may override the DNS server configured by your ISP on your router. There are multiple places where we can define which name servers or DNS resolvers to use, and one may take priority over the other. For this, your browser/OS will send name resolution queries to DNS servers as per your system’s/browser’s/ISP’s configuration. In simple words, it works by translating domain names that you type in your browser’s search bar with their IP address so that your browser can reach the webserver and fetch its contents.ĭNS resolution can work another way as well, i.e., from IP to domain name. DNS or Domain Name Service is the backbone of modern Internet infrastructure on which the World-Wide-Web works.
