Community Consultation on Change to Whois Output for Certain /8 Records
Posted: Thursday, 04 April 2013
ARIN would like to solicit community input on a recent suggestion, 2013.4: Change Whois Output for Certain /8 records. The request asked that ARIN suppress the RIR /8 output in a Whois query when a more specific Direct Allocation (DA) or Direct Assignment (DS) record exists, and instead, display the DA or DS record only.
Command-line Whois clients rely on ARIN's Whois to provide referral server information where it exists, so that the IP address query can be properly referred and resolved. This includes not only ISP Rwhois server information, but also other RIRs' Whois server information.
Queries for IPv4 addresses within /8's that ARIN is fully authoritative for are properly referred. For example, if you look up an IPv4 address in an ARIN /8, ARIN's Whois will provide the direct registration record, as well as referral server information. The Whois clients pick up on this data, and refer queries as appropriate.
The issue is that queries of address records residing within /8s for which another RIR is authoritative for (also referred to as "ERX space") will not make the proper referral due to limitations of the Rwhois referrals. When you query for an IPv4 address in one of these ranges, ARIN Whois currently provides two answers:
- the /8 record of the authoritative RIR; and
- the direct allocation or direct assignment record for the ARIN client
This behavior breaks the referral mechanism of Whois clients.
ARIN has two choices regarding the behavior described above and would like the community¹s feedback on which one is the best course of action, seeking input on the two proposed solutions below:
- Change today's behavior so that if a DA or DS record exists in ARIN's Whois, ARIN will publish only the DA or DS record. If the query does not produce a DA or DS record, ARIN will publish the /8 record of the authoritative RIR and the referral to that RIR's Whois server.
- Continue today's behavior, ensuring that all IP address queries are responded to with the proper RIR information. But the referral server problem described here will continue to be a problem for ARIN-issued registrations in these ERX /8s.
