I wonder what will happen when the pool nears exhaustion globally, not just in Latin America and the Caribbean. A few scenarios come to mind, would love to hear more scenarios/insights: 1. The governments of the world push IPv6 legislation. Everyone invests the resources needed to migrate in a few years, overall everyone's pretty OK with this. 2. Carrier-grade NAT becomes much more widespread. People who need a public IP (mostly p2p users, I guess) pay more for that. Again, overall everyone's pretty happy. 3. Gradual, failover-friendly solutions are deployed. The network becomes fragmented, this plays out like IE6. After a few years, most of the people who matter get tired of this, pull support for IPv4.
