Just for the sake of argument, let's go out on a limb and say (for whatever reason), the ISPs do NOT work out the remaining technical issues and deploy IPv6 in a way that will meet their customer requirements before the IPv4 free pool is exhausted. I see the following options for ISPs: a) stop growing, turn away customers (or, more likely, raise prices to drive out the lower paying customers to free up space for new customers) b) buy up any organization they can find that has address space c) go to the black market to obtain new address space at a market- defined price d) accept new customers only if they come with their own address space e) start selling (potentially multi-layer) NAT'd connectivity Do you see any other options?
