What do they do to update that bogon list anyway -
push a new IOS image?


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bogons is thoroughly out-of-date.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...
