Ben Cox writes in his blog about visualizing IPv4 address space use by mapping the whole IPv4 Internet with Hilbert curves. While the IPv4 address space is quite large it is still small enough to be able to send a packet to each and every IP address. He goes a little into the background of the maths involved and then makes a comparison to the IPv4 address space back in 2012 using data from the Carna botnet.

This is very interesting, much more technical, more detailed, and generally better in all ways except understand-ability.
I do want to note, though... mandatory XKCD [xkcd.com].
To be clear there is a great deal of credit to be had in this analysis and work. I'm not thrilled with how the author claims (and probably indeed did) have the personal revelation of Hilbert curves.
Great job to the author, but credit where it is due as well.

It's therefore Dilbert Curves, or PHB curves.

So you accept he probably did come up with it by himself, but you're not happy that he's claiming that he did so? He might be completely unaware of the XKCD version.

Interesting, but is it accurate? A lot of space in there probably doesn't respond to pings by design, and there is a huge topology above this map representing NAT'd servers that only connect through a single point on this map.
I do have to give him points for humor though. The IPv6 map is pretty funny.
Technically, lunchtime is at any moment. It's just a wave function.

Yeah, I imagine the UK MOD block is a bit busier than indicated, even if they're not really using it.
But then, I'm not sure you want to be running a full nmap of all 65536 ports against the MOD or the US Army blocks, especially not if you have to sit around someplace and wait for it to complete.

$ sudo ping -f -c 1000 nsa.gov
It answered at first but after a hundred or so responses I got "host unreachable" messages.
Now they don't answer pings at all.

In high school, they teach sin, cos and tan, and a few fromulae to apply.
Then you get to university and learn how to map areas under curves in imaginary space, and derive everything from first principles..
This guy learns about Hilbert curves, gets excited and graphs his results.
He even says it has been done before, just not recently.
Is the bit you're not thrilled about his admission of his "discovery"? He learned something, and shared his new knowledge.
I'm a cynic - you just seem to be grumpy.
