That's pretty much the definition of "in use".  If they don't appear in  
the global routing table, then they aren't being used.  I cannot send  
traffic to them; they cannot send traffic to me.

In my recent probe of route servers, I found 22 legacy /8's that were  
partly or completely unused.  I'm a little surprised ARIN/ICANN thinks  
it's a waste of time to even try to reclaim them.
