Portable Resolver

This is the portable edition of Resolver, a simple-to-use networking utility that enables you to look up DNS servers. It comes packed with only a few settings.

Since there is no setup pack involved, you can drop the executable file in any part of the hard disk and just click it to run.

There is also the possibility to save Resolver to a USB flash disk or similar storage unit, in order to run it on any PC effortlessly and without previous installers.

Worth mentioning is that the Windows registry and Start menu do not get updated with new entries, and no extra files are created on the disk without permission, leaving it clean after removal.

The GUI is represented by a single window that provides direct access to all available options, since there are no other features apart from the ones visible.

You can perform a reverse DNS lookup by entering a single IP address or range of addresses, pointing out a local list from the hard disk, or setting a DNS domain to use brute force.

The scanning starts with the click of a button, and you can view the IP address and host name for each identified entry. The results can be saved to file for closer inspection. There are no other notable options available here.

The tool is very light when it comes to CPU and RAM, so it does not affect the overall performance of the workstation. We have not come across any issues in our tests, since the app did not hang, crash or pop up error dialogs. Unfortunately, it has not been updated for a long time.
