Hello Francesco. This is not specific to CoAP, but to all protocols on top of IP. If you would want to inspect forwarding packets, you would need to add that functionality most likely to tos/lib/net/blip/IPForwardingEngineP.nc. Or possibly blip's TrackFlows might be doing it already? If you only want to have snapshots of the routing tables (which might change over time and thus not reflect each IP fragment's path), you could use CoapBlip's CoapRouteResourceC.
