[ppml] Policy Proposal 2006-3: Capturing Originations in Templates - to be revised

The ARIN Advisory Council (AC), acting under the provisions of the ARIN 
Internet Resource Policy Evaluation Process (IRPEP), has reviewed Policy 
Proposal 2006-3: Capturing Originations in Templates and has determined 
that while there is no community consensus in favor of the proposal 
there is consensus that the proposal should be revised and discussed 
further. The AC made this determination at their meeting at the 
conclusion of the ARIN Public Policy meeting on April 11, 2006. The 
results of the AC meeting were reported by the Chair of the AC at the 
member meeting. This report can be found at 
http://www.arin.net/meetings/minutes/ARIN_XVII/mem.html

The AC will work with the author of the proposal to make the community 
suggested revisions and return the proposal to the PPML for further 
discussion.

The current policy proposal text is provided below and is also available

Policy Proposal 2006-3: Capturing Originations in Templates

Policy statement:

ARIN will collect an optional field in all IPv4 and IPv6 address block 
transactions (allocation and assignment requests, reallocation and 
reassignment actions, transfer and experimental requests). This 
additional field will be used to record a list of the ASes that the user 
permits to originate address prefixes within the address block.

ARIN will produce a collection of the mappings from address blocks to 
ASes permitted to originate that address block, The collection will 
consist of a list where each entry will consist, at a minimum, of an 
address block, a list of AS numbers, and a tag indicating the type of 
delegation of the address block. This collection will be produced at 
least daily.

ARIN will make the collected mappings from address blocks to AS numbers 
available for bulk transfer in one or more formats chosen at its own 
discretion, informed by the community's current needs. This data will 
not be subject to any redistribution restrictions -- it may be 
republished or repackaged it any form. Should ARIN choose to use WHOIS 
bulk transfer as the bulk form of data access required by this 
paragraph, the address block to AS mappings will not be subject to any 
redistribution restrictions, but the remainder of the WHOIS data will 
remain subject to the terms of the then-current AUP regarding bulk 
access to WHOIS data.

ARIN may also make the collected or individual mappings from address 
blocks to AS numbers available in other forms, possibly query services, 
chosen at its own discretion, informed by the community's current needs. 
ARIN may require agreement to an acceptable use policy for access to the 
data in these forms.

Policy Rationale

Origination of prefixes by ASes that have no authority for the 
origination is a recurring problem in the Internet routing system. A 
list of authorized prefix originations would be beneficial to operators in

    * constructing routing filter lists to counter bogus originations,
    * interacting with customers requesting routing of a prefix, and
    * diagnosing routing problems.

A list of authorized prefix originations is also the necessary first 
step for any known solution for securing the routing system.

Prefix originations can be stored in routing registry RPSL route 
objects. However, the authority for addresses and for ASes belongs to 
the RIRs. There is presently no mechanism to translate ARIN's authority 
for number resources to an IRR. Furthermore, operators have been less 
than diligent in creating and maintaining route objects. Capturing the 
prefix origination authorization in number resource registrations with 
ARIN has two main goals:

    * benefit from the scrutiny with which ARIN verifies initial 
requests and authenticates subsequent transactions, and
    * inherit the operators' self-discipline in completing resource 
requests and transactions.

As an additional benefit, this could take a step toward populating the 
IRR with data known to be accurate.

The intended use of this data means that both query for individual 
entries and bulk access to a list of the collected entries, without 
restriction on redistribution, is required. This policy requires that 
the additional data be provided through the usual whois query service 
and some bulk access service that has no restrictions. It permits ARIN 
to provide the bulk access through the existing bulk whois service if 
the new additional data is not subject to the bulk whois AUP 
restrictions. The policy does not limit ARIN to providing only those two 
services (whois query and unrestricted bulk access); other additional 
services may be developed at ARIN's discretion.

It is expected that entries in the list of collected entries will 
include at a minimum the present NetRange and NetType attributes, with a 
new attribute, perhaps named OriginatingASList, for the list of 
permitted originating ASes.

This policy will presumably be incorporated into NRPM section 3.4.

Timetable for implementation: Within sixty (60) days of approval.
