That's a mighty fine question: the link I referenced
is the most recent I was able to find, and its list of
bogons is thoroughly out-of-date. In the interest of
long-term reachability, I would call on Cisco to
remove the IANA-UNASSIGNED blocks from the autosecure
filters.
This will only get worse: consider how bad the GWF
problem is now with the antivirus-response-spam...
