My definition for ipv4 adresses exhaustion is: IANA and RIR's have no more unallocated blocks, so everything is left to the free market. If its consequences will be catastrophic or imperceptible is something I can't imagine. I would love to see Google's and Facebook's risk models for the next years, since they are those who could be more severely hit by this.
Being more specific, do you think it will be impossible to buy a public IP address for any price?
If not, then in what sense will it be exhausted?
