We could assert that the TTL is an indication of distance traveled.
you might hypothesize it. but the wide variance in per-hop rtt would seem to belie that.
Maybe one should record the TTL and Address Family of all packets received from the internet ('inbound') at the next NANOG or IETF?
we have large bodies of traceroute and ping results in various stores, mlab, atlas, mawi, ... it is the analysis to test your original hypothesis which baffles me.
I'm not sure if milions traceroutes to all kinds of places are a good dataset to begin with. I'd try to look at natural / organic traffic, such as can be caught at a dual-stacked CPE or webserver. The majority of the traffic my employer carriers is not traceroute packets but other stuff. When will you have the paper ready for publishing? :)
