Dave mentioned:

#At one point we were on a very constructive path towards enumerating the 
#characteristics of fast flux networks and thus defining the varieties of 
#such networks. I really wish we would go back to that enumeration and 
#complete it very analytically and dispassionately.

I continue to be quite pleased with the Mannheim definition for 
fastflux (see "Measuring and Detecting Fast-Flux Service Networks,"
http://www.isoc.org/isoc/conferences/ndss/08/papers/
16_measuring_and_detecting.pdf , URL wrapped due to length), and I've yet 
to see an example where it provides an incorrect "false positive" 
classification of a non-fastflux domain as fastflux.

For those who'd like to try a quick test, hotnoun.com (yet another
Canadian Pharmacy pillz domain) currently scores 341.58 at
http://www.uoregon.edu/~joe/fastflux/simple.cgi , well above
the 142.38 cutoff threshold even on just a single pass...

17 unique ASNs

Mannheim score = 341.58

Could we agree to use the Mannheim definition unless/until someone
else proposes something else that is empirically based and which
seems to do a better job of identifying these domains? The Mannheim
test is simple, fast, objective and seems to provide good
discriminatory power.
