I'm very impressed by this project: http://www.theregister.co.uk/2013/03/19/carna_botnet_ipv4_internet_map/ http://internetcensus2012.bitbucket.org/paper.html http://internetcensus2012.bitbucket.org/images.html
A hardcore but, as many note, 'necessary' strategy if one wishes to get such a comprehensive map of the (IPv4) Internet. You can't expect millions of people to install and use port scanning software - potentially breaking the law in their juristiction - to contribute to your mapping project. So a 'malware' (if you can consider it that) is the better means to acheive that coverage. The anonymous researcher(s) provide 68M traceroute records and 9TB of scan data for download. 420 000 hosts were infected by scouring for default passwords (also using telnet). Routers were a common target. First, find your external Internet IP here: http://www.hostip.info/ And then type it into the 'Add Marker' field in their impressive Hilbert Browser: http://internetcensus2012.bitbucket.org/hilbert/index.html Cheers, -- Julian Oliver http://julianoliver.com http://criticalengineering.org -- Too many emails?
