18.104.22.168 - 22.214.171.124
126.96.36.199 - 188.8.131.52
For Mac users (Lion):
System Preferences > Network

Click the DNS tab, and then click the "+" icon under DNS servers to add in one or more of the above static DNS IPv4 settings.
Click "OK" and make sure to hit "Apply".
Follow these instructions to add in static DNS IP settings:
My apologies, I don't have a Windows machine in front of my to walk you through the steps quickly.
