Among outstanding challenges to Internet-wide topology map- ping using active probes is balancing e ciency, e.g. induced load and time, with coverage. Toward maximizing probe utility, we introduce Ingress Point Spreading (IPS). IPS utilizes ingress diversity discovered in prior rounds of probing to rank-order available vantage points such that future probes traverse all known paths into a target network.We implement and deploy IPS to probe 49k random pre xes drawn from the global BGP table using a distributed collection of vantage points. As compared to existing mapping systems, we discover 12% more unique vertices and 12% more edges using 50% fewer probes, in half the time.
