Changing DNS settings manually could be really a cumbersome process and in fact most of the people even don’t have any idea how to make changes to DNS server settings. So if you want to get rid of that lengthy and complicated process then here is a very handy free tool to try your hands on, its called DNS jumper.
DNS jumper allows you to easily switch among various DNS server settings, like that of Google public DNS, Open DNS, Ultra DNS and some others. DNS jumper is very easy to use, just run the application and it will show you up number of DNS servers to switch to. (See the screenshot below).
Simply a click on any of the desired DNS server will activate it.
