[Irtf-rr] IP Address Distribution

[Xiaowei Yang]

You may want to look at the following paper:

Observed structure of addresses in IP traffic, by  Eddie Kohler,
Jinyang Li, Vern Paxson, and Scott Shenker. 

Proceedings of the 2nd Internet Measurement Workshop (IMW 2002),
Marseille, France, November 2002, pages 253-266.

It is an interesting read. The paper uses a multifractal model for IP
address structure. Intuitively, a large block of IP addresses is
allocated to an Internet registration, which in turn allocates
sub-blocks to other organizations. This is a fractal process. I think
it is possible to develop a simulator from this model.

Hope it helps!
