After talking with APNIC/RIPE, it looks like that if we ask nicely we can get high-quality BGP-peering graphs for the entire Internet (not 100% complete, but it's the same data they use internally). Spend some time thinking about exactly what kinds of attacks we wish to harden against. Once we

Hi Virgil, It appears that vizAS detects connections between ASes when they are observed as adjacent on paths reported by Route Views [0]. When I construct AS-level routing maps (e.g. as in [1]), I combine Route Views data with the AS-level topology produced by CAIDA [2]. The CAIDA topology is

> They're also likely to be wiretapping magnets. That's an interesting point. Can we go deeper into this? Does this mean that, everything else being equal, the good locations for Tor nodes also happen to be the good locations for surveillance tapping points? If yes, my first thought was that

I'm at an APNIC conference in Jakarta, and they demoed a new tool which shows the interconnections (peering + transits) between AS numbers within a given country (will eventually work for regions). URL: http://labs.apnic.net/vizas/ Left-panel is IPv4 and right-panel is IPv6. Here is the fellow
