There are many public DNS services, each returning different results for users around the world. If you're not sure which DNS you should use and you're looking for a quick way to access the best available ones, you probably need something like DNS Jumper. It's a simple application that requires no installation and will immediately replace any DNS configured on your computer.
With so many free and public DNS offers on the web, a situation of slight confusion has arisen for users. Which DNS should you use? Or, on the other hand, is it necessary to change DNS? The only way to know is testing them all, or at least the most important ones. Manually configuring each DNS can become a tedious task, especially when you need several minutes of browsing between changes to check if there's a tangible benefit with a new configuration.
How to change DNS easily
DNS Jumper isn't an overly elaborate tool, but it fulfills its goal very simply: reducing DNS change to a single click. In the list you can find examples of the most important DNS servers, such as OpenDNS, Google, Comodo, Level 3, and Ultra DNS. With just one click you'll see in your network connection properties that the DNS has changed, and the rest is checking how well your connection responds to name resolution.
Performance will depend entirely on each user's location, the type of connection you have, and your computer's configuration. In some cases, certain DNS servers may have a negative impact on performance, but DNS Jumper will let you test them all in minutes. You can use the ping command as a reference, or turn to the utility called namebench to find out which DNS is fastest for you.
DNS Jumper takes up just under 1 MB and requires no installation, so it's ideal for carrying on a USB drive. The ideal case would be not having to change DNS, but no matter how hard providers work to deliver stable and fast DNS, a problem can always appear.
Changing a DNS involves two things: entering the values manually, and remembering them, which isn't always easy. DNS Jumper solves both problems without any negative effect we've been able to detect. Once you have chosen a DNS, it's very unlikely you'll need to keep this application, but before that, DNS Jumper will help you determine which DNS are worth it for you, and which aren't.
