Who Pwns The Internet? (Take Two, Part Two)

I actually got these done over the weekend, but I’ve been kinda busy. After taking a more, ahem, principled approach, France seems less dramatic

France by AS

but still pretty impressive. If you take a close look you’ll see I’ve also had a crack at adding the AS’ owner as well (not 100% reliable, if anyone knows how, let me know!). The UK depends on one less AS than before

and I can do Fiji

I still can’t do the world, though – but now the problem is that dot chokes on the graph.


  1. This is completely pointless Graphviz abuse. The charts are unreadable.

  2. On the contrary! They make quite pretty little pictures of a bunch of flying saucers traveling across the ether. The little self-referential arrow atop each node makes a great little bridge bubble.

    One addition that might make the graph more immediately appealing would be to color-code the flying saucers – er, sorry, nodes – to mark any outliers in terms of being the center of connections, or ones that only have a few connections. The ownership data is great, although that’s a truly huge task to get it all.

  3. Hi Ben – you have relative URLs for the graphs, so they fail in my RSS reader (there is no etc).

  4. That UK AS graph is concealing a lot of symmetry. If you put .uk in the middle than arranged the ASes in an octagon around it — perhaps use the twopi graphviz filter?

    Perhaps. But who’s to say that even denser ones won’t reveal some interesting structure?
