Dear colleagues, Policy proposal 2023-01, " Reducing IXP IPv4 assignment default size to a /26", is now in the Review Phase. This proposal modifies the default size of IPv4 assignments for IXPs from a /24 to /26 and clarifies the return of the assignments previously issued for their IXP peering LAN. The RIPE NCC has prepared an impact analysis on this proposal to support the community’s discussion. You can find the proposal and impact analysis at: _https://www.ripe.net/participate/policies/proposals/2023-01_ _https://www.ripe.net/participate/policies/proposals/2023-01#impact-analysis_ And the draft documents at: _https://www.ripe.net/participate/policies/proposals/2023-01/draft_ As per the RIPE Policy Development Process (PDP), the purpose of this four-week Review Phase is to continue discussion of the proposal taking the impact analysis into consideration, and to review the full draft RIPE Policy Document. At the end of the Review Phase, the Working Group (WG) Chairs will determine whether the WG has reached rough consensus. It is therefore important to provide your opinion, even if it is simply a restatement of your input from the previous phase. We encourage you to read the proposal, impact analysis and draft document and to send any comments to address-policy-wg@ripe.net before 28 July2023. Kind regards, Angela Dall'Ara Policy Officer RIPE NCC
