Iljitsch,

	In deed there were ERX unused space that were divided among RIRs, I think it is referred as "various ERX" (pointed out by Tore).

	There were also ERX space transferred from ARIN DB (used to be in InterNIC's) to RIRs because legacy holders were in the RIR region:

	When you talk about "unused" legacy space are you talking about the "various" space or to the legacy space that is currently assigned but the holders just require part of it? 

Regards,
