New threats from the Internet emerging every day need to be analyzed in order to prepare ways of protection against them. Various honeypots combined into honeynets are the most efficient tool how to lure, detect and analyze threats from the Internet. The paper presents recent results in honeynet made of Dionaea (emulating Windows ser- vices), Kippo (emulating Linux services) and Glastopf (emulating web- site services) honeypots. The most important result consists in the fact that the differentiation among honeypots according to their IP address is relatively rough (usually two categories, i.e. academic and commercial networks, are usually distinguished, but the type of services in commer- cial sites is taken into account, too). Comparisons of results to other similar honeynets confirms the validity of the paper main conclusions.
