How to flush your DNS cache on Windows and Linux

Your device stores DNS information for recently visited sites in a temporary cache. This speeds up browsing by reducing queries to external DNS servers. When DNS records change, your cached information becomes outdated and causes loading problems.

You will clear your DNS cache to force your device to fetch current DNS records. This fixes loading issues during website development when DNS changes happen frequently.

Before you begin

You need administrator access on Windows or sudo privileges on Linux.
We recommend clearing your browser cache after flushing DNS to remove all outdated records.

Ubuntu uses systemd-resolved to manage DNS caching. You will run a command in the terminal to clear cached records and verify the operation completed.

Open a terminal window.
Press Ctrl+Alt+T or search for Terminal in your applications menu.
Run the flush command.
Type sudo systemd-resolve --flush-caches and press Enter. This clears all DNS records stored by systemd-resolved.
Enter your password.
Type your account password when prompted and press Enter. The command runs with administrator privileges.
Verify the cache was cleared.
Run sudo systemd-resolve --statistics to display cache statistics. The current cache size should show zero entries.

Your Ubuntu DNS cache is now cleared. The system will query DNS servers for fresh records on your next request.
