Partial map of the Internet based on data from November 24 rd 2003, taken from http://opte.org/maps (accessed on February 5 th 2020). Each line is drawn between two nodes, representing two IP addresses. The length of the line is indicative of the delay between the two connected nodes. Lines are colour-coded based on Class A allocation of IP space (Asia Pacific -Red Europe/Middle East/Central Asia/Africa -Green North America -Blue Latin American and Caribbean -Yellow RFC1918 IP Addresses -Cyan Unknown -White).

... us move from "natural", organic networks, to cyber-networks, which are numerous as well. A remarkable example of a digital network is the Internet (see Fig. 2 for visualisation). In this network, nodes are physical computers, linked by cables. The large-scale topology of the internet is complex, as it is a self-organizing system whose properties cannot be traced back to any global blueprint or chart [24, Chapter 3]. The World Wide Web is a virtual network of information, living on the ...

These monsters can still be analysed using other techniques, which are discussed ...
