Using wireshark eth.src and ip.src and binding to eth.dst and ip.dst you get an semi-self organized map of devices on the network.
Once you make all IPv4 into CIDR /24 and /16 you have a compressed routing view of the network allowing the trace from traffic generation to Internet in very complex networks.
The ideal view is the Hierarchical view showing interface <> IP Source <> interface <> IP Destination including external networks.
Color coding should demonstrate a row of interfaces, followed by a row of networks followed by yet another row of interfaces.
