Dear colleagues,
In November 2023, I shared with you during the RIPE meeting and on this
mailing list that the RIPE NCC intends to assign Autonomous System
Numbers (ASNs) from an undifferentiated 32-bit AS Number pool, as
defined in the Autonomous System (AS) Number Assignment Policies.
I am pleased to inform you that this change has been successfully
implemented. The option to choose between a 16-bit or 32-bit AS Number
as been removed. When submitting a request, the RIPE NCC will assign the
next available AS Number from the undifferentiated allocation pool.
Kind regards,
Marco Schmidt

Dear colleagues,
During the RIPE 87 Address Policy working group session yesterday, I
presented the topic of AS Number assignments, specifically addressing
a policy in place since 2010. According to this policy, assignments
should be made from an undifferentiated 32-bit AS Number allocation pool.
https://www.ripe.net/publications/docs/ripe-679#ASnumbers
Before this policy became active in 2010, the Address Policy WG
recognized that many providers were not ready to exclusively work with
32-bit ASNs, mostly due to technical constraints. A verbal consensus
in 2009 suggested that the RIPE NCC would temporarily continue using
two pools of 16-bit and 32-bit AS Numbers. The plan was to attempt to
extend the global policy by 12 months, but this effort was never
undertaken. To date, the RIPE NCC remains the only Regional Internet
Registry (RIR) employing this temporary approach.
Observing that other RIRs have successfully issued AS Numbers from an
undifferentiated pool for many years without technical challenges for
operators, the RIPE NCC plans to phase out the current temporary
approach. The intention is to align with the policy and issue AS
Numbers accordingly.
No objections were raised during the working group session. However,
for transparency, we want to inform working group members who couldn't
attend the RIPE meeting. The presentation can be viewed here:
