- This map might explain it better than any statistics could ever hope to: The red hot spots show where the most devices that can access the internet are located.This map was made on August 2 by John Matherly, the founder of Shodan, a search engine for internet-connected devices.
- Matherly, who calls himself an internet cartographer, collected the data to put it together by sending ping requests to every IP address on the internet, and storing the positive responses.
- A ping is a network utility that sends an echo-request message (known as a packet) to an IP address — the internet’s version of “hey, are you there?
- Although Shodan is well-known for its potentially shady practices that prey upon insecure networks, ping requests — the same thing your internet provider uses to test speed and data loss — are completely benign, Matherly says.
- Armed with the new process, Matherly plans to track the changes in the globe’s internet connectivity over time.
