I'm still busy processing stuff, but some interesting plots are these:

A very special implementation of random:

This is bind4 I think:

W2K Nameserver I think:
        http://ds9a.nl/pub/210.244.182.61.53.png

The X axis plots seconds since midnight (I started measuring around half
past 10PM, ended around 11AM the next day). The Y axis is the DNS query id.
In the upper right hand side you can find the IP address of the recursing
nameserver.

The W2K nameserver might be smart enough to generate id's per remote IP
address, and therefore be deterministically safe, instead of 'just random'.

I really hope to publish something soon but my spare time is not that
copious..
