I don't believe I am changing the qualifying criteria. At least not significantly.
What I am changing is the amount of space a qualifying entity can get.
By increasing the maximum amount of space allowed (possibly dramatically),
if anything, this should reduce the impact on the DFZ.
However, I really don't think that the IPv6 DFZ size is of tremendous concern.
I think that the DFZ size is much more of an IPv4 issue. The IPv6 DFZ, even
when IPv6 is fully deployed is likely to be less than 20% of the current
I think that excessive focus on DFZ size has flawed ARIN policy for years
and including it in the rationale for this policy would only serve to further
