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.”
