The trick to solving the v4 exhaustion & v6 inertia is going to be getting these two numbers closer to each other :
Percentage of available address space announced: 44.4 Percentage of allocated address space announced: 62.9
I expect you are referring to reclaiming unused address space. Doing so might push further into the future the dates on which the IANA and RIR pools are emptied. The measure of how far those dates are pushed is how much of the 'allocated but unannounced' space is actually used but not seen. Not all IP networks are connected directly to the public Internet and so not all the 'allocated but unannounced' space is available for recovery. Regards, -- Leo Vegoda IANA Numbers Liaison
