One ought to be careful doing this, as operators are likely running MPLS networks nowadays which may not expose the internal hopcount accurately if at all :)
True, but in this case I really only care about the visible hops anyway; invisible hops do not affect the calculations for setting the outgoing TTL. Also, thanks to Jon Brewer for pointing me at the Internet Census; their "traceroute" file is part of the answer, but unfortunately it is not exactly comprehensive; e.g. 192.203.154.0/24 only appears 48 times in the whole file. So sample data is still welcome. -Martin
