Resolver

Resolver is a tiny and simple software tool which was built specifically to aid people in looking up DNS servers for a given IP address or range, as well as save results to a file.

The installation process is not a necessity, as this tool is portable. As a result, the Windows registry and hard drive are not going to be updated with new entries, and no leftovers are going to remain on the disk after you discard it.

It is also important to keep in mind that if you copy the program files to an external data device, you make it possible to take Resolver anywhere with you, and run it on any computer you come in contact with, by simply clicking the EXE.

By using this utility, you can easily find out the PTR (pointer record) of any IP address or range, by performing a reverse DNS lookup. It is also possible to perform this operation by uploading an IP list, in a TXT format.

Results are going to be displayed in the main window with information such as IP address, hostname and type, and you can easily save them to a custom location on the hard drive using a TXT file extension. No other notable options are supported.

To conclude, Resolver is a pretty handy and reliable piece of software. It does not put a strain on the computer’s performance as the amount of resources used is minimal at any point. The interface is minimal and suitable to all types of users, while the response time is good.
