Infrastructure?...That’s easy! RIPE ATLAS: 11k++ probes (02/2020) Routeviews: 31 collectors https://atlas.ripe.net/results/maps/network-coverage/ http://www.routeviews.org/routeviews/index.php/map/ 3

Problem/Chall llenge BGP Collector DPs Vantage Point (VP) CPs 4

Single-homed Network Not so easy to find! BGP VP Collector CPs DPs 5

Co Co-located VPs BGP Collector PEERING Testbed VP CPs DPs 6

Dataset Results DPs: 80K destinations CPs: BGP dumps every 2h 6 VPs in PEERING ~ 10/20 days 2 Additional VPs ~ 8 months Currently ~ not running ~ undisclosed (soon) 7

Conclusions Infrastructure • Need for co-located VPs • Peering Testbed (few full RIBs) • Look for more co-located VPs Results • Few lies, but not zero! • Some exceptions with high MM rate • Look closer at the remaining mismatches 8
