is it common to proxy register route objects for the purpose of grouping them for use in an as-set
by Steven Wallace 27 Sep '24

27 Sep '24

Greeting, One of the DDoS mitigation providers we work with creates proxy route objects for its customers’ prefixes. These route objects specify a common origin ASN rather than the actual origin ASN that would be seen in routing tables. Their rationale is to bind the prefixes to a single ASN, allowing the entire set of customer routes to be announced via an as-set. Is this a common approach? Just curious. thanks, steve Steven Wallace Director - Routing Integrity Internet2 ssw(a)internet2.edu

Question about the use of NO_EXPORT in BGP route announcements
by Sriram, Kotikalapudi (Fed) 25 Sep '24

25 Sep '24

For some IETF work in progress related to Source Address Validation (SAV), it is useful to know the purposes for which NO_EXPORT may be attached to routes announced in BGP, especially towards transit providers? I know it makes sense for an AS to announce an aggregate less-specific prefix to transit providers and peers without NO_EXPORT while announcing some more-specific prefixes (subsumed under the aggregate) with NO_EXPORT towards customer ASes. But are there good reasons when an AS might announce a prefix (route) to a transit provider with NO_EXPORT attached? The IP address space in consideration here is meant to have global reachability.

Call for participation in an online academic survey
by KANEMATSU Hiroaki 23 Sep '24

23 Sep '24

Hello NANOG community, My name is Hiroaki Kanematsu, a Ph.D. student at the Graduate School of Informatics, Nagoya University (Japan). I am conducting an online academic survey on professionalism and ethics among IT professionals. I have already conducted this survey in Japan among the IT engineers' community including JANOG, and would like to invite members of the NANOG community to participate and make comparisons. The survey URL is here: https://questant.jp/q/Y2LMFXGV The survey has a maximum of 55 questions. It will take 10-20 minutes to complete. And it will be open until the end of next month, September 30th (Monday) JST. I plan to publish the results of the survey in an academic paper and will provide some form of feedback to the NANOG community. Your cooperation will be greatly appreciated. Thank you, -- 兼松宏明 (Hiroaki Kanematsu) 名古屋大学大学院情報学研究科社会情報学専攻

Re: Hurricane Electric now supports ASPA for route filtering

Hi Mike,>Hurricane Electric now uses ASPA to do hop by hop checking of AS paths >when deciding which routes to accept when building prefix filters. >Here is an example of a route failing the ASPA check. >44.31.69.0/24,rejected,AS path 4635 9002 945 7480 38254 38254 38254 >38254 38254 ASPA record exists for 7480 and 945 is not listed as a provider. >44.31.73.0/24,rejected,AS path 4635 9002 945 7480 ASPA record exists for >7480 and 945 is not listed as a provider. Thank you for doing and sharing this work. I am interested in this ASPA-invalid example and have a few questions. Q1: Has this example been sent to the network operator of AS 7480? A confirmation from 7480 would help us understand the reasons behind, e.g., a route leak or forgetting list 945 as a provider in the ASPA.Q2: I would like to do some ASPA-based verification analysis as well. I do not operate a network or a router, so I need to download ASPA data from public sources by myself. Do you know where I can download ASPA objects and the payload?>I'm sure Job will be able to give much better or more accurate guidance regarding ASPA software, protocols, and terminology.I copies this email to Job as well :-)Best,Lancheng

Retirement of FTP protocol support at ARIN? (was: [ARIN-consult] Consultation for the Retirement of FTP Protocol Use at ARIN)
by John Curran 20 Sep '24

20 Sep '24

NANOGers - ARIN has opened a consultation on removing support for FTP as an access method (in preference to HTTP/HTTPS) for our data archive – please see the attached consultation and provide feedback to the arin-consult mailing list if you have strong opinions on such a change. Thanks! /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <info(a)arin.net> Subject: [ARIN-consult] Consultation for the Retirement of FTP Protocol Use at ARIN Date: September 20, 2024 at 3:16:23 PM EDT To: <arin-consult(a)arin.net> ARIN is seeking feedback from the community (https://arin.net/participate/community/acsp/consultations/2024/2024-5/) on retiring FTP protocol support, which serves data from ftp.arin.net. ARIN has operated an FTP protocol service for various reports and templates since its inception. All the data that is currently provided via FTP is also available over HTTP and HTTPS. ARIN is working to remove redundant and seldom-used services to allow future efforts to focus on the improvement of core services, reduce residual technical debt, and increase our security posture. Removing the FTP protocol aligns with these objectives. ARIN will not remove the data or change the existing directory structure. HTTP/HTTPS transport will continue to reference the data as it does today. ARIN intends to remove FTP protocol support on or after 31 March 2025. We are interested in knowing: - If there are ARIN customers who have a reliance on FTP that cannot be satisfied by obtaining data from ARIN via HTTP/HTTPS? - Does setting the date for 31 March 2025 provide sufficient time for customers who use FTP to move to HTTP/HTTPS? Please provide comments to arin-consult(a)arin.net. You can subscribe to this mailing list at https://lists.arin.net/mailman/listinfo/arin-consult. This consultation will remain open until 5:00 PM ET on 4 October. ARIN seeks clear direction through community input, so your feedback is important. This information will help with our planning and decision making. Thank you for your continued support to improve ARIN’s services. Regards, John Curran President and CEO American Registry for Internet Numbers (ARIN) _______________________________________________ ARIN-Consult
