[..] I couldn't make it up from the slides or the terse text, but I am wondering how much information you can really deduce from BGP, yes it says "they don't have that prefix", but for the rest, even if an ISP has a prefix it doesn't mean that any packet can flow from A to B. Doing traceroutes from a remote site doesn't help as that is just C to A or B. Better "Internet Hubble Telescopes" are therefor: RIPE TTM: http://www.ripe.net/test-traffic/ RIPE RIS: http://www.ripe.net/ris/ TTM is deployed globally around the world and does traceroutes/pings/bgp monitoring and a lot more to see where problems are, you can get a peek at what it can show you at: http://www.switch.ch/network/ttm/ courtesy of SWITCH in Switzerland. If you want an "IPv6 Hubble" you can check up GRH which has provided that kind of information for quite some time already. Greets, Jeroen Attachment:
