How do you activate DNS cache?

Activating the DNS cache isn’t a direct process you initiate manually within Chrome’s Chrome Net Internal DNS tool, as the browser and operating system handle caching automatically to speed up website loading. However, you can manage and refresh the DNS cache using the Chrome Net Internal DNS feature to ensure it’s functioning optimally. To do this, open Chrome and type chrome://net-internals/#dns in the address bar, then press Enter. This page provides insight into how Chrome handles DNS, including cached entries. While there’s no explicit "activate" button, you can clear the existing cache by clicking the "Clear host cache" button, which forces Chrome to rebuild the cache with fresh DNS data. This effectively reactivates the caching process as the browser re-queries DNS servers. Additionally, ensure your system’s DNS client service is running (e.g., restart it via Command Prompt with ipconfig /flushdns on Windows) to support Chrome’s caching. Regularly clearing the cache via this tool, as outlined in the blog, helps maintain performance and avoids stale data, aligning with the troubleshooting steps to enhance your browsing experience.
