It's a directory of resources which makes it is as much "DNS" as
Kazaa/Gnutella/whatever-p2p-warez-thing allows one to find resources
(files) on the Kazaa p2p network.

One fundamental thing is that there is no 'root' as such a trusted
delegation can never exist and you will never know if the resource you
are trying to access is really the one you want or is just a spoof of
the one you asked for. With DNS, even without DNSSEC, if you typed the
correct name, you can be pretty sure that that is the real one.

Greets,
