[address-policy-wg] 2023-01 Review Phase (Reducing IXP IPv4 assignment default size to a /26)

Hi Nick, all,

The proposal does not modify existing numbers (50%) or the "special circumstances". Both are in the current policy already (see old policy text 6.1 .4). I think the changes you propose should be done in a separate policy proposal as they are an addition to this policy proposal rather than a change.

Nevertheless RIPE has clarified how they handle the 50% issue currently (see Marco Schmidt's mail from mid May):

Thus, this issue is not urgent and can be discussed separately. I hope that answers open questions.

Regards,
Matthias

I agree with Nick here regarding 1.
These magic numbers should really be fixed.
