World map of internet connections

“Where is the internet? This map might explain it a little – 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, who calls himself an internet cartographer. He 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?”.

That part was relatively easy compared to the visualization process, says Matherly. “It took less than five hours to gather the data, and another 12 hours or so to generate the map image.” For that, he used the programming language Python.”

Some questions for Code Clubbers (note, these may test your knowledge of the countries of the world!):
  • What’s a “Cartographer”? What do you think an “Internet Cartographer” is?
  • What is a Ping request? Can you explain it a bit more clearly than in the text above?)
  • What is Packet Data? (year 6’s – no excuses, we discussed this last year!)
  • What do you think this map tells us about the location of most of the internet devices in the world? Why?
  • Explain why it doesn’t look like Canada has many internet-connected devices?
  • Do you have any questions about whether the data collected to make this map is reliable? I have lots and I don’t know the answers to them without knowing more details about how the data was collected!
