Comment 2 for bug 234629

Hi bascule, thanks for pointing out the regex but it's hard or
impossible to concoct one that stops LAN access. Blocking numeric IP
addresses isn't sufficient. I argee this plugin is dangerous by default
and yet nowhere in the documentation, or during selection of this
plugin, does it warn the user to consider whether their network set-up
would be vulnerable. I think that's a bug that needs addressing.

Chatting on the supybot channel, I was told it should be obvious to
anyone that this can happen and that's what network DMZs exist for.
Well, it wasn't obvious to me since there's a lot of plugins and
considering the security implementations of each of them would take
hours.
