The first part of this thesis deals with an approach of designing and developing of application for IP geolocation using various geolocation databases. Methods of geographical location of network devices and amount of available data provided by chosen commercial and freely accessible geolocation databases are presented. The data are summarized with focus on methods of obtaining information about IP addresses from various databases. In the paper there are also presented ways used to develop the Python application and its parts, which can be easily reused in other programs. The command line program was created to demonstrate that all parts of the developed application work properly. The whole application is freely accesible under the conditions of the MIT license, published on GitHub (https://github.com/tomas-net/ip2geotools/) and in the Python package index PyPi. The second part of this thesis deals with the description of cyberthreats and the use of developed application to mass geolocation of IP addresses that are listed in chosen freely accessible lists as sources of email spam or cyberattacks. Geographical analysis of cyberattacks sources shows countries of origin. Results of analysis are presented in graphs and maps.
