How do I update / flush / reset my DNS settings from Windows?

2 Answers 2


Run IPCONFIG /FLUSHDNS from an elevated command prompt.

This will flush your DNS cache, but not change your settings. If you actually want to change your DNS server, you will need to either set it statically, or run IPCONFIG /RENEW if your DNS server's settings have changed,
