A map created by Texas-based internet cartographer and computer scientist John Matherly at search engine Shodan shows significant disparities in internet access across the world.

The map is dotted with red, bright spots and blackouts. While the glowing red and orange areas denote the densely connected cities and towns, the blue and black spots signify the sparsely connected areas.

Matherly told TIME magazine that it took around five hours to ping all IP addresses on 2 August. The map then took more than 12 hours to create.

If you zoom into India in the map, it shows the country to be dotted with orange and green marks, denoting a fairly well connected network. However, China, owing to its great firewall is a black space.

The United States and European countries obviously seem to be most connected. Africa and central Asia’s connectivity is limited to urban cities.

Explaining how he made the map, Matherly said : ‘The data was generated using a stateless scanner used to create Shodan (a computer search engine that he founded)'

‘A free, open-source scanner called Zmap is readily available for anybody that wants to do it themselves, and the map itself was generated using the Python matplotlib library.

However the map isn’t complete or comprehensive  due to various censorship and security restrictions.
