Your computer and browser save DNS answers for a while to load websites faster. After you change nameservers or DNS records, your device may keep using the old answer. Clearing the cache makes it look up the new one.
Clearing your cache only affects your own device. Other people may still see the old version until the change spreads, which can take up to 24 hours. See How long DNS changes take to work.
Open Command Prompt (press the Windows key, type cmd, and press Enter) and run:
You’ll see “Successfully flushed the DNS Resolver Cache”.

Clear your browser’s cache too

  • Chrome or Edge: go to chrome://net-internals/#dns (or edge://net-internals/#dns) and click Clear host cache.
  • Any browser: open your site in a private or incognito window, which ignores most saved data.

Still seeing the old site?

  • Your router or internet provider may also cache DNS. Restarting your router can help, or try another network such as mobile data.
  • Check that the change was made in the right place. See Where to edit your DNS.
