Public DNS Server Tool

Public DNS Server Tool is a tiny and portable piece of software which allows you to seamlessly switch to another DNS server for your network interface card.
It does not come loaded with complicated features or configuration settings, making it suitable to all type of users, regardless of their previous level of experience with such apps.

No installation necessary

Since installation is not a requirement, you can save the program files to a custom location on the disk and just click the executable to launch Public DNS Server Tool. Another option is to copy it to a removable storage unit (like a USB flash drive), in order to run it on any PC with minimum effort and no previous installers.
What's more, unlike most installers, the tool does not modify Windows registry settings or create extra files on the disk without your permission, so no traces are left behind after its removal.

Intuitive interface and options

The GUI is user-friendly, consisting of a normal window with a neatly organized layout, where you can select the network interface card (or all of them), view the current DNS server, as well as pick one from the list to connect to, after inspecting their descriptions and addresses.
Changes are applicable with the click of a button. In addition, you can back up the registry scripts to file and restore them at a later time if you change your mind. Unfortunately, the software does not gives you the possibility to set custom DNS servers.

Evaluation and conclusion

There were no stability issues throughout our evaluation, as Public DNS Server Tool did not hang, crash or pop up error messages. It runs on low CPU and memory, so it does not affect the overall performance of the PC. Although it is not feature-rich, the program provides users with a fast and effective method to switching to another DNS server, and it can be used with ease by anyone.
