DNS Jumper is capable of modifying your DNS server address based on the types of network cards you have and the types of DNS services you select. After you select your network card and preferred DNS services, you can surf the internet using that particular DNS setup. When you feel like returning back to your PC's default DNS configuration, you can select the 'Default' DNS service. There's even a handy tool where users can check the response time of their preferred DNS server addresses, or pick the fastest DNS for your connection. The software also offers other DNS-related tools, such as a backup option and a DNS flush option, which is useful for refreshing DNS server address(s) when your internet connection is experiencing connectivity issues. It also comes in many languages, from the default English to more obscure languages worldwide such as Romanian and Vietnamese. Overall, it has a professional and neat GUI layout, so learning to use this software does not take time.
