You are encouraged to discuss all Draft Policies on PPML. The AC will
evaluate the discussion 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.
“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 unique AS Numbers depends upon their need (or lack
thereof) to interconnect with other organizations’ Autonomous Systems.
“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 AS Numbers under the “unique
routing policy” requirement, because they don’t understand what “unique
routing policy” actually means in practice.
“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 AS Numbers. Additionally, clarification that some
organizations may have a unique need for an AS Number outside of
utilizing a unique routing policy, such as one implemented using, for
example, a protocol such as Border Gateway Protocol (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
“If a unique AS Number is not required for a given network design, one
or more of the AS Numbers reserved for private use should be utilized.”
Replace
“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) 2. A multihomed site”
with
“In order to be assigned an AS Number, each requesting organization must
provide ARIN with verification that it requires a unique routing policy,
such as a plan:
To originate announcement of IP Number Resources via an accepted
protocol (such as Border Gateway Protocol) from an AS Number different
than that of its upstream provider;
To multihome a site with one or more Autonomous Systems; or
To use an AS Number to interconnect with other Autonomous Systems.”
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 are issued based on current need, as set out in this section 5.”
