I'd like to thank the group for the responses and help with this issue. I find it ironic that Randy's study actually uses 96 space.
The amazing/sad thing is that people have been facing and fixing the same problem for more than 4 years. How many times does a network have to fix their static bogon filters before coming to the realization that those filters are a bad idea?
So, where are static bogon filters appropriate? (loaded question perhaps) I ask because just about every 'security expert' and 'security whitepaper' or 'security suggestions' has some portion that speaks to "why it's a grand idea to have acl-lines/firewall-policy tp block 'bogon' ip space" (for some definition of 'bogon' of course).
