IPNetInfo

Lots of useful information is attached to IP addresses. If you want to conveniently access this information, I invite you to try NirSoft’s application IPNetInfo. Enter one or multiple IP addresses in the application and it will quickly gather info related to those IPs.

The system requirements for running IPNetInfo are as simple as they come. You just need to have an internet-connected PC that is powered by Windows (anything from Windows 98 onward).
To get IPNetInfo up and running you do not have to complete an installation process. You just need to download an archive, extract its contents, and run the IPNetInfo executable.

Launch IPNetInfo and you will be presented with a “Choose IP Addresses” prompt. In the large text box at the top, enter the IP addresses or the URLs you want. If you’re going with the URL option, make sure to check the “convert host names to IP addresses button."

After that, IPNetInfo will analyze your input and present IP info on its interface. Country, network name, owner name, contact name, address, host name, and other info is presented to you by IPNetInfo. All this info can be saved as a TXT file or as an HTML report.

IPNetInfo is freeware. You can use the tool for free for as long as you want. You can freely distribute the tool if you want to.

Give IPNetInfo one or a list of multiple IPs and the application will quickly collect useful information on those IPs.
