How to Flush your DNS Cache on your computer
Flushing DNS cache is a way to troubleshoot DNS lookup issues and web page issues from your computer.
The reason to flush DNS Cache is to ensure that your cache has the latest correct data. Usually it is important to do this when there are server changes, moves or updates, or you are relocating your hosting or email to a new server to an new ip address or a new server hosting company.
Typically DNS Cache is something that is handled between your PC and the DNS server it is attached to. However, devices such as firewalls may also cache DNS entries on behalf of your PC. These devices may need to be flushed as well.
