[arin-ppml] Policy Proposal 112: Utilization of 10.4.2 resources only via explicit policy

Hi George,

This /8 is not given to ARIN based upon need. It is given based upon its 
status as the last one available from the free pool. There is no 
implicit assumption that it should go to fill needs in the same manner 
as all previous ones. I see no reason that it should be squandered in 
the same manner as all the rest have without at minimum due 
consideration as to possible alternates.

If there wont be enough time to work out policy for this last /8 while 
holding it in reserve, then there definitely will not be time to work 
out policy before it is consumed -- too late. On the other hand, the 
policy process does have the ability to move quickly, such as the 
emergency pdp process.

4.10 is possibly not enough. We do not know yet.

I agree that there are some reasons to hold addresses in reserve for transition items, but the existing policy already makes provision for that in the form of a /10. It is impossible to say that we as a community will know (and more importantly, agree on) 100% of the reasons why addresses should be allocated in the 10.4.2 endgame and can get them all documented in the policy process in a reasonable amount of time so that this is not an overly inflexible and limiting rule for ARIN staff and users of IPv4 space.
