Data communication in the Internet is based on the borderless interplay of Autonomous Systems (ASes). An AS abstracts one or multiple IP networks, which may be globally distributed, but is owned by an organization located in a country. Current research on the Internet structure mainly focuses on a global perspective or considers local, intra-domain properties. In this paper, the authors analyze nation-centric subsets of the Internet taken from the AS-level graph of Germany. Each subset reflects a public or industrial sector.
