I deal in IDS'es more than IPSes. So, I feel the domain blocks would
be better suited for the dns server rather than the IPS. Although I
imagine they could work equally well on an IPS. Still, I don't know if
there are generic signature detection of fast-flux networks for
IDS/IPS systems.
I attended a brief at NDSS on fast-flux detection methods. The
research presented was new and wasn't able to be automated. The
presented research was an initial framework. So, it was a started to
automating the process.
I wish I had more time to invest towards this problem, because I
believe it is an excellent and difficult one to solve. If anyone is
working on this problem, I'd be interested.

Test Your IDS
Is your IDS deployed correctly?
Find out quickly and easily by testing it
with real-world attacks from CORE IMPACT.
