Dear Tore,
I question the wisdom of abolishing the need-based mechanism for sub-allocations exclusively, when (to the best of my knowledge) all other mechanisms to obtain number resources in all other regions are need-based.
Need-based princip make sense only until RIR has IPv4 for allocations. I understand that it was many years and it is as habit.
Just see how many transfers in other RIRs. This mechanism work not very good for now.
How come? In any case, if the transfer policy is broken somehow, why not fix it?
Transfers good for permanent transfer. For temporary transfers better option sub-allocations while if you transfer IPs for some time than you get them back and see that they are in spamhouse and other black lists. In case of sub-allocation IPs in your control and you can regulate it. -- Kind regards, Alexey Ivanov LeaderTelecom B.V.
