InterDomain SSH Server Topology

(IP addresses are anonymized)

Each of the nodes in the graph represents a host or set of hosts from either an academic institution's network (.edu), business network (.com), or a /8 (Class A) network. A single edge is used to represent all of the known_hosts relationships from a source network to a destination network. 162 nodes that have less than 10 edges are excluded. Edges from a.edu are colored in red.
