Actually if that'd be done world-wide with all address-space not publicly routed - and therefore easily to replace with 10.0.0.0/8 - we'd have sufficient IPv4 for the next decades ... Just a brief look into the routing-table on my router and I see 10 complete /8 (so called public IP-Space-prefixes) which are completely not announced and another 4 /8 with less then one /21 announced.... and I do not want to know how many of the large /8 to /14 announcements are actually routed into a blackholes, as there are no real users on large parts of those nets.
Without speaking for or against the policy, I'd like to point out that there definitely are cases where unique addresses are required, despite not announcing the route to all of autonomous systems. There are plenty of RFCs explaining why. It should also be obvious that even if 50 /8s were recovered they would not be enough to meet demand. There are about 7 billion people on Earth and more than half do not yet have Internet access. IPv4 is not a sustainable resource. Regards, Leo Vegoda
