IPInfoOffline

IPInfoOffline is a lightweight and portable piece of software that fetches country information on given IPs. It comes packed with an intuitive set of features that can be figured out by all user categories.
As there is no installation involved, you can drop the executable file in any location on the hard disk and just click it to run.
There is also the possibility of saving IPInfoOffline to a USB flash drive or similar storage unit, to be able to run it on any PC with minimum effort and no prior installers.
An important aspect to take into account is that the Windows registry does not get updated with new keys, and no additional files are created on the disk without your consent, leaving it clean.
The UI is made from a normal window with an intuitive layout, where you can get started by typing or pasting IP addresses to process. The tool can exclude duplicate IP addresses and blocks.
Once this step is finished, the main frame automatically populates a list with the source and target IP, organization, assigned data, country, country code, and index for each entry.
Selected items or the entire list can be exported to HTML, XML, TXT or CSV format for closer inspection. In addition, you can use a search function when dealing with large amounts of data, as well as access an online page with major IP addresses blocks (ordered by country).
IPInfoOffline has minimal impact on computer performance, running on low CPU and RAM. It is very responsive to commands and works well, without causing the OS to hang, crash or pop up error dialogs. We have not come across any issues throughout our evaluation.
In a nutshell, IPInfoOffline gathers country information based on IP addresses and features exporting functions. It can be used by anyone.
