It's fine to request address space for private networks.

It's fine to connect such private networks to some other networks, even 
one sometimes referred to as the Internet, frequently or infrequently.

However, it is not fine to assume you could any form of addressing at all 
and expect it to be reachable.

If you connect to the Internet, you play by its rules, not by the rules of 
your private networks.
