You are encouraged to discuss all Draft
Policies on PPML. The AC will evaluate the discussion in
order to assess the conformance of this draft policy with
ARIN's Principles of Internet number resource policy as
stated in the Policy Development Process (PDP).
Specifically, these principles are:
* Enabling Fair and Impartial Number
Resource Administration
* Technically Sound
* Supported by the Community

Draft Policy ARIN-2021-3: Private AS
Number and Unique Routing Policy Clarifications
Problem
Statement:
At ARIN 47, staff identified three
points of potential confusion with current text in NRPM
Section 5: AS Numbers.
1. “Sites that do
not require a unique AS Number should use one or more of the
AS Numbers reserved for private use.” Some customers are not
aware that their need for a unique AS Number depends upon
their need (or lack thereof) to utilize the AS Number on the
public Internet.
2. “In order to
be assigned an AS Number, each requesting organization must
provide ARIN with verification that it has one of the
following…A unique routing policy (its policy differs from
its border gateway peers)…A multihomed site.” Few customers
qualify for an AS Number under the “unique routing policy”
requirement, specifically because they aren’t aware of what
“unique routing policy” applies to.
3. “AS Numbers
are issued based on current need. An organization should
request an AS Number only when it is already multihomed or
will immediately become multihomed.” All ARIN delegations
are based on current needs, and some customers aren’t aware
they need network plans when they request an AS Number.
Additionally, clarification that some organizations may have
a unique need for an AS Number outside of utilizing a unique
routing policy, such as BGP.
Policy statement:
In Section 5 -
Replace
“Sites that do
not require a unique AS Number should use one or more of the
AS Numbers reserved for private use.”
with
“Private ASNs
should be used only when there is no plan to use them on the
public Internet.”
Replace
“1. A unique
routing policy (its policy differs from its border gateway
peers) 2. A multihomed site.”
with
“1. A plan to
connect their network using a unique routing policy, such as
Border Gateway Protocol (BGP) 2. A network requiring routing
policies to be deployed which are unique only to that
network”
Replace
“AS Numbers are
issued based on current need. An organization should request
an AS Number only when it is already multihomed or will
immediately become multihomed.”
with
“AS Numbers
should be requested when an organization has network plans
ready and is either planning to use a unique routing policy
(such as BGP) or has a unique need for an AS Number.”
Timetable for
implementation: Immediate
