I do not understand why the slow start policy is relevant to large scale IPv6 deployments on existing IPv4 networks. I would have expected that in most cases APNIC, or the relevant NIR, would already have information about the network on which IPv6 is being deployed and would just need details of the new addressing plan, as per 5.2.3.b.

Thank you for the explanation. It had not occurred to me that two years would meet the minimized overhead requirements set out in section 3.7 of the policy. It would be interesting if the Secretariat could explain how the policy requirements in 3.7 were implemented as accommodating just two year's planned growth.
