[ARIN-consult] Fw: [ARIN-Suggestions] New Suggestion - ACSP 2016.4 - Waiting List for 2 Byte ASNs

[David Huberman]

Apologies, but I have this data analysis done, and I dont want to lose it.   I can resend when the consultation officially opens.


I just did a quick data analysis of the DFZ found on one of my routers.

There are 601,729 unique routes originating from and transiting through 53,511 ASNs.

71,170 routes (11.8%) originate from or propagate through a 4-byte ASN.
There are 10,244 (19.1%) unique 4-byte ASNs in my copy of the table.

Given this data, I'm unclear why the registry should be treating 4-byte ASNs as anything but a single contiguous pool, as policy currently states.

We received the following suggestion on 18 March:

Suggestion Details:

Description: Waiting list for 2 Byte ASNs

Value to Community: One member said to me:

Ticket from ARIN "We have noted your request for a 2-byte ASN. ARIN is
out of 2-byte ASN's in its inventory. We get them returned voluntarily
from time to time. If we have one at the time of issuance, we will issue
it to your organization. If we do not have a 2-byte in inventory at that
time, your organization will receive the standard 4-byte ASN. "

Member comment "if they are really out - a waitinglist would be nice...."

On 30 March, we sent the following response to the submitter:

Thank you for your suggestion numbered 2016.04 - Waiting List for 2 Byte
ASNs.

Background

The NRPM included instructions in the past for ARIN staff to remove any
distinction between 2-byte and 4-byte in the issuance of AS numbers.
This particular policy language has since been retired in the NRPM.

Staff has followed policy regarding issuance of AS numbers, but has
often had lower numbered, classic 2-byte, AS numbers available over
time. We would either receive them in our new delegations from the IANA,
obtain them from customer returns of AS numbers, or through revocations
of AS numbers due to non-payment of registration fees. Although ARIN
expects to no longer receive AS numbers from the IANA inside the classic
2-byte range, we do expect to continue reclaiming them through returns
and revocations going forward.

Some AS number requests today continue to specifically ask for an AS
number from the classic 2-byte range. In those situations we relay to
the customer that we have noted their special request and that we will
accommodate it at the issuance phase of the ticket process if one is
available at the time.

The Suggestion

We understand your suggestion is to establish a waiting list for AS
numbers from the classic 2-byte range for those customers who
specifically request one when ARIN does not have them available. This
waiting list would be similar to the IPv4 waiting list for unmet
requests, but managed separately for AS numbers. Organizations would be
placed on this AS number waiting list, and when one became available
through reclamation at ARIN, it would be slated for the organization
first on the waiting list.

Staff Action

ARIN staff can create a waiting list for 2-byte AS numbers if there is
favor from the community to establish one. ARIN staff will open a
consultation on the topic to gather feedback and take appropriate action
based on information received through that process.

Thank you for participating in the ARIN Consultation and Suggestion
Process. We will leave this suggestion open until a consultation has
been completed on this topic and an implementation plan has been
established.

Regards,

Communications and Member Services
American Registry for Internet Numbers (ARIN)
