Community Consultation: Available Methods of Reporting Network Sub-Delegation Information

Posted: Monday, 02 October 2017

ARIN was previously requested via the ARIN Consultation and Suggestion Process (ACSP) to open a consultation to generate discussion about the possibility of sun-setting RWhois support by the ARIN organization. ARIN's initial response to the ACSP indicated we would open a consultation following the completion of the Registration Data Access Protocol (RDAP) specification inside the IETF processes. This work has been completed and the RFC has been published. ARIN took the additional step of implementing RDAP inside its own directory services offering with referral support to the other Regional Internet Registries (RIRs). With this work complete, we are following through with the formalized request to open a consultation on this topic.

In accordance with ARIN's Number Resource Policy Manual (NRPM), Organizations are required to report certain types of customer network sub-delegation information (reassignments and reallocations) to ARIN. Currently there are two reporting methods available. Both are delineated in the NRPM and supported by ARIN's production services. There is also a third possible method of reporting sub-delegation information that could be made available, but is not yet offered.

Method 1: 

SWIP (currently available):  The reporting of sub-delegation information using ARIN's database. This can be done either by submitting a SWIP template, interfacing with ARIN's RESTful API, or by creating a sub-delegation inside ARIN Online using ARIN's SWIP-EZ functionality.

Method 2: 

RWhois (currently available):  The reporting of sub-delegation information on your own hosted and operated RWhois server with referral link information provided in ARIN Whois as part of your own organization's Whois records. In order for a user of ARIN's directory services to view sub-delegation information hosted by an RWhois server, they would have to submit a separate query to that RWhois server, and are not referred in an automated fashion.

Method 3: 

RDAP:  The five RIRs currently use RDAP for referrals to each other's Whois data. Although the specification language of the RDAP could allow it to be used as a third method for the reporting of sub-delegation information to ARIN, it is not currently offered as an option. In order to make this option available, associated registry software would need to be created. This possible method would allow users of ARIN's directory services to view sub-delegation information available on customer hosted RDAP servers in an automated fashion. This RDAP method may also be viewed as redundant to RWhois.

Options Going Forward

ARIN expects to continue offering Method 1 (SWIP) into the foreseeable future. As previously described, we are acting on a formal suggestion to consult with the community about the future of RWhois support, and also have potential options with RDAP.

Question (general): 

Of the three sub-delegation reporting methods listed (SWIP, RWhois, RDAP), which should ARIN support in the future?

Question (SWIP/RESTful API specific): 

The existing RESTful API allows users to report (SWIP) one sub-delegation at a time to be added to ARIN Whois. Should ARIN add bulk-upload features to the RESTful API?

Question (RWhois specific): 

As noted, RWhois servers are not referred to in an automated fashion when users query ARIN Whois. Should ARIN automate referrals to RWhois servers from ARIN's Whois service?

Question (RDAP specific):

If ARIN was to allow the reporting of network sub-delegation information using RDAP, associated enabling software would be required. Should ARIN enable this method by creating an RDAP software suite that would allow ARIN registrants to run RDAP service locally?

The feedback you provide during this consultation will help inform decisions about software tools and support for the reporting of network sub-delegation information to ARIN in the future. Thank you for your participation in the ARIN Consultation and Suggestion Process.
