What I'd be curious to know in the numbers being thrown around if there
has been any accounting of transient address usage. Since I'm spending
I worked with Adlex to update their software to identify and track dynamic
addresses associated with subscriber RADIUS information. At the time,
Adlex (now CompuWare) was the only off-the-shelf software that matched
unique subscriber RADIUS instead of just IP address. It is behavior based,
so not absolutely 100% accurate, but it is useful for long term trending
"bot-like" unique subscribers instead of dynamic IP addresses. I presented
some public numbers at an NSP-SEC BOF. There is a large difference
between the number of unique subscribers versus the number of dynamic IP
addresses detected by various public detectors.
