The Carna botnet was a botnet of 420,000 devices created by an anonymous hacker to measure the extent of the Internet in what the creator called the “Internet Census of 2012”.

Data collection[edit]

The data was collected by infiltrating Internet devices, especially routers, that used a default password or no password at all.[1][2] It was named after Carna, "the Roman goddess for the protection of inner organs and health".[3]

It was compiled into a gif portrait to display Internet use around the world over the course of 24 hours. The data gathered included only the IPv4 address space and not the IPv6 address space.[4][5]

The Carna Botnet creator believes that with a growing number of IPv6 hosts on the Internet, 2012 may have been the last time a census like this was possible.[3]

Results[edit]

Of the 4.3 billion possible IPv4 addresses, Carna Botnet found a total of 1.3 billion addresses in use, including 141 million that were behind a firewall and 729 million that returned reverse domain name system records. The remaining 2.3 billion IPv4 addresses are probably not used.[3][6]

An earlier first Internet census by the USDHS LANDER-study had counted 187 million visible Internet hosts in 2006.[7][8]

Number of hosts by top level domain[edit]

Amongst other, Carna Botnet counted the number of hosts with reverse DNS names observed from May to October 2012. The top 20 Top Level Domains were:
