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).
