Hi there, On my Mac when I go to system preferences, network, choose airport and press advanced. I click the DNS tab and enter my values however my mac will not use them even after reboot! There's nothing wrong with the DNS because when I hookup my iPad to my iPhone via mobile hotspot and I tell the iPad to use a custom DNS and reboot, IT WORKS! Why wont my Mac use the DNS values I gave it to use!? Also, PS I installed the DNS on my router so when I'm at home it works but I need to use this DNS on the go! I'm on OS X Lion btw!
