To clean up your DNS, start by flushing your DNS cache. For Windows, open Command Prompt and type `ipconfig /flushdns`. On a Mac, open Terminal and input `sudo killall -HUP mDNSResponder`. This will refresh your system’s DNS cache. Next, consider updating your DNS server settings to a faster or more secure option like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1). Lastly, regularly clear your browser's cache to ensure your internet browsing isn't affected by old DNS data.
