Map of Internet IPv4 Address Space Growth
This video charts the growth of the Internet by producing a map of which ranges of IP addresses have been allocated in time, from 1982 to July 2014.
The map is divided into a grid of 16×16 squares, each of which is an /8 block of IPv4 addresses, or approximately 16.7 million addresses.
The white area represents unallocated addresses. Olive is IETF reserved, dark olive is multicast. Red and green are allocated addresses. Green addresses were listed as being advertised in July 2014. Red addresses are allocated but not advertised in July 2014.
The map format is inspired by the xkcd map of the same from 2006: http://xkcd.com/195/
The data used to generate the map was taken from Geoff Huston’s « IPv4 Address Report » at http://www.potaroo.net/tools/ipv4/index.html
More specifically, the « Listing of the IPv4 space with status and dates » link.
The Hilbert curve coordinates for mapping an IP address to space were created using Luis Alejandro Gonzalez Miranda’s code from http://forums.xkcd.com/viewtopic.php?t=866
