It's kind of a cool hack, though apparently there are at least two companies that have done it. 2**32 is just NOT a very big number any more, so it's not surprising that somebody has tracerouted all of it (except 10.* and other private spaces.) Depending on how efficient they want to be, there are ways to make the traceroutes take advantage of the fact that they're sequentially scanning, so most locations take the same path as the previous one. I'm probably going to port-scan 10.*, which in this case is my organization's lab network which has 4 locations and could use better documentation. Thanks!
