the risks and constraints that apply to them as part of their business plan. If they don't understand that constructing a business model based on IPv4 address space doesn't deserve to succeed in my view. The imminent exhaustion of IPv4 should be one of those constraints and I thought our final /8 policy was constructed so that the boundaries would be clear and unambiguous to everyone - existing and new users. There have been several policy proposals since we agreed the final /8 policy that have tried to create corner cases and I just wish we'd stop trying to do this. I'll repeat my view that this group should be focussed on policy initiatives that promote and support the deployment of IPv6 where they are needed. Perhaps a sig-policy meeting where there were no proposals tabled might be one way to measure success!
