Map of Internet connected devices on Earth

By sending and waiting for feedback, an American computer scientist has successfully mapped all of the devices connected to the Internet globally.

According to Imgur, the map was completed Aug. 2 by John Matherly, founder of the Shodan search engine in Texas, USA. Martherly calls himself "Internet Mapper", has collected data by sending a "ping" request - a packet of information to every IP address on the Internet, and storing responses to determine the location. the address of that IP address.

"It takes about 5 hours to collect data and 12 hours or more to draw maps," Martherly said. He uses the matplotlib mapping tool of the Python programming language.

The red dots on the map show the highest density of internet connection devices, yellow is the lower. Blue regions have the lowest density and black areas are non-responders.

This map is an updated version of the 2014 map, showing how the Internet connection has evolved over the past two years. The most noticeable developments are India. African countries have relatively low Internet connectivity.

The map also shows that the highest density of Internet access is Europe and the East Coast of the United States. The central United States has low connectivity, mainly due to its low population density. Silicon Valley in California has a high connection density.

Some of the big regions like China shown on the map are black - no Internet connection. According to Martherly, there are some organizations that block feedback.

"Basically not much information can be provided with IPs located in China, which makes mapping very difficult," Martherly said. "The majority will be included in Shanghai or Beijing, although it may be located elsewhere."

According to Martherly, an open-source scanner called Zmap is provided free to anyone who wants to make a similar map. However, he warns that such a tool could be exploited by cybercriminals by sending and receiving packets to anyone connected to the Internet.
