Fastflux is a whois and IP address tracker. It allows you to add and track domains via a web interface.
It will track new A-records for the domains and locate the latitude and longitude information for the IP addresses using the free GeoLiteCity.dat file from MaxMind.
This information is stored in a MySQL database and plotted on a world map using Google Maps.
An easy to use interface allows you to add new domains and view previously recorded whois information and IP addresses.
The Google maps view allows for further inspection of the plotted ip-address. Selections can be made based on the country of interest.
