Owner Shodan search engine pinging the entire Internet and made him a card Bashny.Net

Finder Shodan focused not on finding information on the internet and searching for information on the global network itself - more precisely, about the devices connected to it . With Shodan can search webcams, servers, routers and any other equipment that has access to the Internet, up to systems uaprvleniya industrial equipment, power plants or traffic lights - moreover, many of these systems have very little protection from intruders (or do not have it at all )

Recently Shodan owner John Mezerli decided составить map of all devices , with IPv4-address on the Internet. In fact, to ping all available devices with direct access to the Internet took a little less than five hours. Data processing and rendering maps took twelve hours.



Related maps internet published online Internet Census 2012 in March last year, moreover it contains much more information. However, for her collection of used botnet of nearly half a million computers, and also ping, port scan was performed - re-conduct such scans is problematic because of its volume and apparent illegality. Map of John Mezerli was compiled without the use of a botnet and using only ICMP-requests ping, so these scans can be carried out completely on a regular basis, says Mezerli. With time on such a "fingerprint" of the network will be to trace the dynamics of growth of the Internet in developing countries, as well as the development of the "Internet of Things".
