Flushing your DNS cache is a very easy process that is sometimes necessary to do when your computer is not resolving a particular hostname to the correct IP address, this process will clear any locally stored results that may be out of date and not correctly being updated. This sometimes is the reason that you may be seeing messages such as
ERR_NAME_NOT_RESOLVED in your web browser.
If you're running Microsoft Windows, then all you need to do is run the command
ipconfig /flushdns from the command line. More in depth details and instructions with screenshots on how to flush your DNS on Windows and a variety of other operating systems can be found on our dedicated flush DNS page.
