Easily!? I'm not so sure that is a correct description of the process. Perhaps Leo Vegoda could comment on this point since he had more first hand involvement than I did.
On the whole, these assignments were for one or two /32s. They were unlikely to be useful for anything else. The one network that renumbered didn't have a problem finding a couple of spare /32s from their RIR space. I think I would have seen significantly more difficulties if the assignments had mostly been used or been for /24 or shorter prefixes. The difficulty I experienced in reclaiming 14/8 was finding out who to contact. Once I'd found someone who knew about the addresses there wasn't really any resistance to returning them. That being said, the process took about a year of calendar time, which is more than I had expected. I have been looking at other /8s for about the same time with less success. Regards, Leo
