Sometimes, you think that you are covered on the internets (all of them!), but then I get an email like this to my primary account:

I removed the company that sent the email, not sure that I want to encourage this type of email and account harvesting.
The point is, that someone, somewhere has correlated my different accounts on my various networks to my single email signon. Someone, somewhere knows my that the articles dugg on digg are associated with the pictures that I post on flikr! So, when I don’t post anything, they can check my pictures to find out what I was doing!
They missed twitter, delicious, slashdot, facebook and this blog though! And all of my troll accounts! Thats tood to know that there is some anonymity!
Following up the xkcd.com “comic”, a sweet idea to map the IP address range and their owners into a 2d map (where all adjacent values are grouped together), some bored people over at an email consulting company mapped out the IP addresses and activities using actual CAIDA ‘whois’ data in a scalable google map. CAIDA (The Cooperative Association for Internet Data Analysis) collected the data as seen in the huge png:

The scalable ‘google maps’ like viewing of the Hilbert Table is here:
I should be all Blog2.0 and post this as a trackback, but they don’t have the option.
It is pretty neat to take data that you normally don’t visualize, in this case the assigned DNS IP ranges of organizations and put them together in a way that can make the lay-person understand something new. In this case, you can see the companies that ‘formed’, or at least were the first to embrace, the internet and register whole top level domains! Meaning, of the 4-256 values in a typical IPv4 these companies have a whole first number to themselves.
For example, The Computer Science Corporation ‘CSC’ owns the whole 20.*.*.* address range. Crazy.
