[address-policy-wg] 2019-02 New Policy Proposal (Reducing IPv4 Allocations to a /24)

Hello working group,

The first comments I got back on this proposal all seemed to miss the point of it. Let me explicitly state what this policy is NOT about:
- it is NOT about conserving IPv4 addresses
- it is NOT about postponing the runout date
- it is NOT about extending the lifetime of IPv4

It's purpose is solely about:
- dealing with the returned address space the NCC will get over the years

Under the current policy:
- the waiting list will grow indefinitely
- the allocations given out will consist of tiny fragments
- it will therefore not be of any practical use

This proposal proposes:
- keeping /22 until we run out of /22s
- give out /24s only after that
- this helps to keep the waiting list manageable [1]
- declare everything smaller (longer prefix) than a /24 unusable
- this helps against people getting unusable dust

[1]: see https://ripe77.ripe.net/presentations/71-Andrea_Cima_RIPE_77_APWG.pdf slide 14

Please forget about previous attempts to change allocation sizes. Those were about changing the current allocation policy. This proposal only looks forward to what to do after the current policy becomes unusable. Please focus on that.

Cheers,
Sander
