How long does an IP address remain infected?

One of the interesting questions we get asked at TheatSTOP concerns how long an IP address remains bad once it has been identified as such. The answer is not completely straightforward and varies depending on which threat list it has been put on. Moreover many lists do not have specific "first seen" or "last seen" data on each IP address, rather they simply list the currently active list (where active typically means that they have been identified as bad within the last week or so). Possibly worse for questioner, some of the threat sources we use are distributed under terms that prohibit us from answering the question.
