Patricia will extract info from IPs

Suppose you collect a humongous set of different ip addresses, and they have propoerties such as country, security info, level of trust, login names, urls, etc.

A quick way to build a tree of ip,properties against you can check huge amountsof IPs is by using Patricia algorithm, and the quickest way, for me, is doing it in Perl.

Check out the patricia module (http://search.cpan.org/~plonka/Net-Patricia-1.010/Patricia.pm), and prepare your scripts to build trees.

Once you want to review the porperties of the new bunch of ip addresses, look for matches in the patricia tree strucuture. Fast!!

Site of reference -> Caida.org

One of the sites of reference for Internet Geographers; www.caida.org. I wont describe what is Caida, you need to go and find it yourself. I will only mention that all the projects they do fit in the space of internet geography.

They aim to understand the network and establish a dynamical model of it. TCP dynamics and IP dynamics are frequent words.

Go see the tools section, the projects, papers and conferences. And buy the poster too.
