Is there an RFC or other standards document that clearly states that static
bogon filter lists are a bad idea? While this seems like common sense, there
was just an RFC published on why IP addresses for specific purposes (like
NTP) shouldn't be encoded into hardware.
Using a dynamic feed needs to be codified so that it finds its way into
training classes, documentation, etc. Otherwise, this problem will recur
indefinitely.
