How to flush your DNS cache

Did you know your computer has DNS cache which stores stores the locations (IP addresses) of web servers hosting websites you’ve previously visited?

If the IP address of the web server changes before the entry in your computer’s DNS cache updates, you may find you’re no longer able to access the site, or you may be viewing the site from an old server.
