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.
