You do it on your PS3. On the XMB (the main menu) go to Settings->Network Settings->Internet Connection Settings. Hit X when it tells you what you're about to do. Then when it says "Select a setting method." choose "Custom". The system will probably prefill all the next screens with the settings you already have so go through each one of them until you get to a screen that says "DNS Setting". Instead of Automatic, choose Manual. Then you will come to the screen where it will ask you for a Primary and Secondary DNS and that's where you put those numbers down (184.108.40.206 and 220.127.116.11) then you can continue on to the end and it will test the connection and see if that worked.
