But that is true now. If you choose to have private IP numbers, you must
not pass them on to the general Internet.
RFC1597 attempts to institutionalize this, in the theory that the rest of
us can predict and be assured that you will use ONLY those assigned private
numbers. Since that is an entirely unsafe assumption, RFC1597 is inclined
to lull us into taking a 'filter only this small set' approach rather than
'pass only this small set'. I.e., the backbone routers should allow
through only those IP numbers that are known to be safe, rather than filter
only those known to be unsafe.
