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.

Here is a 2006 survey to compare.

How long did it take to run the entire range?
about a month, since I ran it at about 6000 addresses / sec checking distinct addresses 4 times (round robin) or 1500 finished / sec
You might be interested in ZMap: With a 10gigE connection and either netmap or PF_RING, ZMap can scan the IPv4 address space in under 5 minutes.
Comparison is the thief of joy 🙃
Though if I push my scanner hard it could probably do 16k/sec on the single core and 1gig connection it is on. The problem is how reliably I could do 16k/sec over the network, since a good portion would be dropped even if the host’s hardware could keep up.
I’d probably need access to enterprise-level equipment that could handle the routing load if I were to do it in 5 seconds lol, it’s insane they managed to do that
Masscan was made for this as well ;)
every IP address
every IPv4 address
They’re working on the IPv6 part right now, just don’t ask when it’ll be done.
ipv6 would look like a starless sky
IPv6: a dark image
I left details out to be less verbose.
