Just because an address block isn't advertised in the DFZ doesn't mean it isn't 
being used.

There's nothing wrong with using globally unique (i.e. registered) IP addresses 
internally for your own use.  Again, this is a standard use case.

This whole conversation is veering into "lets keep IPv4 going for as long as we 
can" when we should be putting all our effort into IPv6 adoption.  There is no 
other future for the Internet.  Talking about "freeing up" "unused" IPv4 is 
futile.

Exactly.

But feel free to join the people on the “let’s use Class E” bus.
