Draft Policy ARIN-2021-8

Deprecation of the ‘Autonomous System Originations’ Field

Status: Under Discussion
Shepherds: Alicia Trotman, Anita Nikolich

Current Text (26 October 2021)

Problem Statement:

In the last two decades ARIN has developed multiple services which provide mechanisms for Internet Number Resource holders to publish information about their routing intentions.

The optional ‘OriginAS’ field was invented before RPKI existed in practice. , At that time,ARIN’s Internet Routing Registry (IRR) followed a weak authorization model compared to available and in use today such as RPKI. The ‘OriginAS’ data was an improvement compared the other mechanisms that were available at that time.

However, there are some issues with consumption of the data in the OriginAS field:

Consuming the ‘OriginAS’ field in a high-scale automated pipeline is challenging. The consumer needs to enter into a ‘Bulk Whois Data’ agreement with ARIN, download a multiple-gigabytes XML file (which is only generated once a day), parse this XML, and then extract the OriginAS field. Querying objects one-by-one via the HTTPS interface does not scale well.

Policy statement:

Remove Section 3.5 “Autonomous System Originations” of the NRPM in its entirety.

Comments: This should be performed before ARIN eliminates the ARIN-NONAUTH.

Timetable for Implementation: One year after ARIN Board adoption.

Policy Term: Permanent
