After that my connection became extremely slow(It was taking hell lota time to open even google)..So i changed the settings back to how it was previously!! and nw it works..can anyone please tell me what all these terms mean!! And are these addresses same for any bsnl broadband user throughout india?? or does it depend on where you are or which telephone exchange do you come under?
