Systems and methods for route finding in networks and/or in a network of networks. A server is communicatively coupled to a datastore, which hosts a model of an industry of Internet infrastructure as a graph. Nodes of the graph represent physical components that make up various networks that, collectively, interconnect with one another, infrastructure components that house the physical components, and entities owning and/or operating any of these equipment and facilities. Edges of the graph, which are preferably directed in nature as defined by labels, represent the relationships between the physical components. The server hosts and employs a route-finding application that utilizes the graph to search for an optimal path between nodes of the graph responsive and according to user-specified criteria.
