Re: Won't happen in my lifetime
As the ISPs have to pay for IPv4 allocations for their customers - if they can get them at all - it will be driven by ISPs providing it to their customers.
Irrelevant. The ISPs in the US and EU have sufficient IPv4 address space, and the market is already saturated so there is little room left for further growth thus little need for larger IPv4 address space.
The entrenched players like it this way because they can use this as another barrier to entry, as a new ISP that lacks IPv4 address space needs to acquire it somehow before they can expand into new markets. So they have no reason to push IPv6 adoption and make things easier for smaller, hungrier competitors.
