Hi Alistair,

There is still unicast address space that isn't allocated by any RIR?

Seriously though, check all your bases. Is not the space unallocated
by all RIRs or just the one you expect to hold it?  If you have a
transit provider that's not playing by the rules, contact their
transit providers to complain and if you still don't get satisfaction,
I'd name and shame the lot of them. Failure to filter bad actors is
how prefix hijacking happens.
