Network mapping or Internet mapping is the study of the physical connectivity of the Internet. Network mapping determines the servers and the operating systems run on them of internet-connected networks. It is not to be confused with the remote discovery of which characteristics a computer may possess (operating system, open ports, listening network services, etc), an activity which is called network enumerating and is more akin to penetration te...

Network mapping or Internet mapping is the study of the physical connectivity of the Internet. Network mapping determines the servers and the operating systems run on them of internet-connected networks. It is not to be confused with the remote discovery of which characteristics a computer may possess (operating system, open ports, listening network services, etc), an activity which is called network enumerating and is more akin to penetration testing.
Images of some of the first attempts at a large scale map of the internet were produced by the Internet Mapping Project and appeared in Wired magazine. The maps produced by this project were based on the layer 3 or IP level connectivity of the Internet (see OSI model), but there are different aspects of internet structure that have also been mapped.
More recent efforts to map the internet have been improved by more sophisticated methods, allowing them to make faster and more sensible maps. An example of such an effort is the OPTE...
