Hello Peter,
I love this feature. I think it is a one-of-a-kind thing and hopefully many more people will think the same.
However, it will need a lot of documentation and explaining.
I have a couple of high-level questions:
* Does it make sense to give the user the choice for the threshold?
It seems to be a difficult question because it requires exact knowledge what this feature actually does. My fears are that people just set this to something like “9” and the feature would become ineffective. What use-case is there to change this?
* Selective announcements: Should this necessarily live in the proxy? Why do we not generate a filter for the firewall?

This patchset adds two new features to IPFire's web proxy, taking advantage of the Autonomous System information we have at hand by using libloc.
The proactive Fast Flux detection is especially worth noticing, as even most expensive (= advanced?) security suites do not provide similar protection, especially not in a proactive manner.
By simply enumerating the distinct amount of Autonomous System Numbers a FQDN ultimately resolves to, we are able to deny access to malware distribution sites, phishing sites, C&C servers, and other cybercrime stuff hosted on Fast Flux setups abusing cracked machines around the world - even before the FQDN or any IP address involved is flagged as malicious by any security vendor.
