<br>
A new RIPE Policy Proposal, 2023-01, "Reducing IXP IPv4 assignment <br>
default size to a /26"<br>
is now available for discussion.<br>
<br>
The goal of this proposal is to extend the lifetime of the IXP IPv4 <br>
address pool and to motivate IXPs to implement the exchange of IPv4 <br>
routing information over IPv6.<br>
<br>
You can find the full proposal at:<br>

<br>
As per the RIPE Policy Development Process (PDP), the purpose of this <br>
four-week Discussion Phase is to discuss the proposal and provide <br>
feedback to the proposer.<br>
<br>
At the end of the Discussion Phase, the proposer, with the agreement of <br>
the WG Chairs, will decide how to proceed with the proposal.<br>
