IP Info Offline is a totally free tool that lets you view information on IP addresses without needing to be connected to any kind of external server.
For each IP address it gives you the following information: location, range of the IP (from where it starts to where it ends), organization (RIPE, ARIN, APNIC, LACNIC or AFRINIC), assignation date, geographic location (name and country code).
Once IP Info Offline has all this data related to the IP addresses, you can copy it to the Windows clipboard or directly to TXT, HTML, XML or CSV formats.
