1. A method of analysis of an actual or planned routed computer network comprising:

  • producing structured routing device data in electronic memory which represents the actual or planned routed computer network and in which respective stored level three protocol routing device port addresses are associated with respective routing device names;

    identifying based upon the structured routing device data respective first level three protocol subnets associated with respective first level three protocol port addresses, wherein identifying includes sequencing through the structured routing device data to identify respective level three port addresses associated with a first level three protocol and determining respective first level three protocol subnet functions associated with such identified first level three protocol port addresses in the actual or planned routed computer network as represented by the structured routing device data; and

    producing first connection information in electronic memory indicating respective associations between respective identified first level three protocol subnets and respective first level three protocol port addresses.
