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.

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.
