You can now download the network diagram for the USMA internal network from the dataset website. Please note, this is the planning document used just prior to the execution of CDX 2009. There may have been changes made at the last minute to the network that were not annotated on the network diagram. USMA utilized NAT (double-NAT in some cases). We will be uploading the final router configurations within the next week. A combination of the configuration files and the network diagram should help most folks correlate IP addresses in PCAP files to actual host IP addresses on the network. Let me know if there is something else that would be of additional help in this regard.
