I pinged every IP address that wasn’t reserved. The image is 8k by 8k and is re-encoded as an AVIF to be friendlier to mobile devices. Like every other survey done, it is using a Hilbert Curve to convert the linear address space to a contiguous 2d space. The hotter the colors (blue is coolest), the denser the ping responses were.
(If you are interested the full-resolution pyramidal-tiled TIFF can be downloaded and viewed in QuPath on desktop. I’ve also compressed the ping response data into its own format down to about 150 MB. PM me for a link)
Here is a 2006 survey to compare.
Some observations: Big Tech (USA) is in the top left. US government allocations, for the most part, did not respond to any pings. And maybe you didn’t realize this before, but Multicast (Class D) & Class E consume a whopping 12% of the IPv4 range.
How long did it take to ping the whole world?
Or more specifically, what is the sum of all latencies divided by the number of responses times the total numer of requests sent (to scale up for the ones that didn’t reply, assuming their average latency would have been similar to the total average)?
