  • Unsurprisingly, the map is very similar to the World Population Density Map: https://luminocity3d.org/WorldPopDen/#3/20.00/10.00

  • Comparing land area to IP address assignments is one of the sillier visualizations I've ever seen. I can't imagine what this is intending to convey. Should Siberia have more IP addresses than all of Europe?

  • Ran across a comment a while ago on some fun "IPv6 math":

        On the surface of the Earth [land+water], there are 8.4 IPv4 addresses per km². Not counting the oceans, that would be 28 IPv4 addresses per km² land.

    IPv6 gives 10¹⁷ addresses per mm² (yes, square millimetre).

    In terms of volume, 10⁸ IPv6 addresses per mm³ throughout the Earth.

    A second way of thinking about it:

    * Stars in the Milky Way: 400 Billion

    * Galaxies in the universe: 2 Trillion

    * So (4x10¹¹)x(2x10¹²) = 8x10²³ stars in the universe.

    * Size of IPv6 address space: 3.4x10³⁸

    * Find the ratio between addresses and stars: 3.4x10³⁸ / 8x10²³

    IPv6 offers about 430 trillion times more addresses than estimated stars in the universe. From Tom Coffee's presentation "An Enterprise IPv6 Address Planning Case-Study":

  • The only thing that surprised me was that Canada was so small compared to other Western countries. But I suppose that might be an artifact. The map shows IPv4 proportional to land area, but a "fair" allocation would have IPv4 proportionate to population, not land area, and I'd assume Canada is (overall) less densely populated than most other developed countries.

  • The fact that we have yet to fully deprecate IPv4 should be considered a great failure in the tech industry's competence.

  • IPv6 got some real traction in the last decade. From around 10% adoption up to 50%. It's not dead, like many are claiming. It works fine, just keep implementing it.

  • From a Georgist perspective, IPv4 is actually a form of land (it's a finite "natural resource", although that's not quite proper), and you could make a case for "land rent" being taxed on the addresses. This is the same as radio broadcast frequencies, web addresses, actual land, un-mined gold/oil/coal/whatever, and other finite natural resources that create monopolistic tendencies.

  • India: 47M

    China: 358M

    Both countries have roughly the same population. The IPv4 problem has been swept under the rug with CGNAT and a normal person doesn't even notice it. But it sucks. Forget having a dedicated IP, even on a broadband connection, you don't get a public IP that's truly yours. According to IPInfo[1], there are around 1,000 users sharing my IP. I get flagged for malicious activity, and online gaming is impossible without a Tailscale relay.

    Of course, much of this comes down to the bad luck (+ policies) of developing late, when most IPv4 blocks had already been allocated. But it's pretty unfair how US DoD, Apple, Ford, and others [1] are sitting on enormous IPv4 blocks they'll probably never fully use, and may never sell. Meanwhile I am sharing a single public IP with a thousand strangers.
