What the immediate upstream may think would be irrelevant. *If* there is
*ever* consensus within the RIPE community to have the NCC reclaim
blocks, there would have to be mechanisms in place to enforce the
decision. That would most probably involve a quarantine period for
reclaimed prefixes during which transit providers in the region would be
asked to black-hole the space.

It only takes a handful of large transit providers to black-hole a
prefix to render that address-block useless.

There are more than enough transit-providers on contract. The immediate
upstream of the reclaimed block alone makes no difference.


The question isn't if it can be done or not, but whether the RIPE
community as a whole really wants such a scheme to be implemented.
