So if you’re running into an issue where you need to flush DNS on your machine, there are a couple ways to do so… the two most common ways for me at least (long live the command line interface!) are to either pop open a run dialog in elevated permissions mode on a Windows box or open up a term shell on OSX.
For Windows, open an elevated permissions run dialog and then type:
For Mac OSX, open a term shell and then type:
sudo killall -HUP mDNSResponder
Happy flushing and hope that your DNS records start resolving soon.
