Clue should also be provided to the network operators who actually listen
to route advertisements for these networks.  We use private address space
here for various things, some of which are even production, but you've
never once seen us leak the advertisements for them.  And if we did make
the mistake of allowing them out, no one should ever listen to us about
them.  Blocking traffic from reserved space at your borders and not
listening to route advertisements for reserved space should be common
practice.  I would hope anyone clueful enough to be on this list would
know this already.
