Hurricane Electric now supports ASPA for route filtering
by Mike Leber 08 Sep '24

08 Sep '24

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. These were found on the HKIX route servers (this example may be gone by the time you look at it, or it may exist for a while): https://routing.he.net/index.php?cmd=display_filter&as=4635&af=4&which=reas… For Hurricane Electric, the ASPA filtering is part of the prefix filter generation used for all customers and peers, which is responsible for the decision to accept a prefix. The vast majority of the route filtering decisions occur at this stage. We will shortly be adding ASPA reactive filtering which will monitor for prefixes that we have accepted that later become invalid. (Possible gross oversimplification ahead.) ASPA (Autonomous System Provider Authorization) is a relatively easy to understand add-on to RPKI that allow an ASN to create a record that lists which ASNs can be providers for that ASN. The concepts are "customer" (an ASN) and "providers" (a list of ASNs). How did we do this? How can you do something similar? You should already be familiar with RPKI and should set up an RPKI validator, ideally one with ASPA support. Test to see that you can validate origin and prefix pairs so that you know you have the RPKI validator working. Then do research regarding your specific RPKI validator to dump all the ASPA objects currently being published. The following article is an interesting starting point for the concepts involved and to help you play around: https://as51019.com/posts/aspa-bird2/ In the blog post the experimenter was building AS path filters for bird using ASPA records from a dump from routinator. If you wanted a routing daemon with builtin early stage ASPA support, I'm told you can use openbgpd with rpki-client. I'm sure Job will be able to give much better or more accurate guidance regarding ASPA software, protocols, and terminology.

Hurricane Electric now supports "Never via route servers" (the peeringdb flag)
by Mike Leber 08 Sep '24

08 Sep '24

Hurricane Electric now supports "Never via route servers" (the peeringdb flag) as part of our route filtering algorithm. Using peeringdb, an ASN may indicate that its routes should never be learned via route servers. As a simple detection method, currently route servers are detected at run time when the first AS hop of a path does not match the peer AS. When checking a path learned from a route server each hop is checked to see if it has "Never via route servers" set to true. Here is an example of a route failing the "Never via route servers" check. 80.96.25.0/24,rejected,received AS path 9009 62350 from a route server and 62350 has indicated that it is never to be learned via route servers (peeringdb flag). This path was learned via the Balcan-IX route servers (this example may be gone by the time you look at it, or it may exist for a while): https://routing.he.net/index.php?cmd=display_filter&as=24745&af=4&which=rea… The "Never via route servers" filtering is part of the static prefix filter generation, which is responsible for the decision to accept a prefix.

Apple Geolocation contact?
by J.R. Raith 06 Sep '24

06 Sep '24

Hi All, I have a laboratory in my department which thinks it's in central Russia when using Apple Maps on macOS and iOS devices. (I've also seen it in Google Maps on macOS, which I assume is GMaps getting its location from the OS). The lab has also reported Bhutan, Malta, and the equally exotic Ohio. This room is a shielded from GPS and cellular signals, but may pick up neighboring Access Points. Step outside of that specific room and you're back in Colorado. Phones and laptops keep setting their timezone wildly wrong and we're having graduate students and faculty missing classes/meetings. I've tried swapping out the Access Point in the lab. I've tried dropping a pin in Apple Maps and reporting the location as incorrect, repeatedly and with separate devices. I started looking at geolocatemuch, but I'm not sure that's the problem in this instance. The NAT IP we come from shows proper location in infosniper. I'd love to chat with an Apple person about how to solve it. Wish I could get frequent flyer miles for this... Thanks, J.R. Raith _________________________________________________ Network Administration & Desktop Support JILA Computing - University of Colorado, Boulder

Important ARIN Operational Change re Automatic IRR object creation (was: [arin-announce] Reminder - Automatic Creation of Managed IRR Route Objects upon RPKI ROA Generation Coming Soon)
by John Curran 04 Sep '24

04 Sep '24

NANOGers - As announced in the recently closed consultation, ARIN Online will support automatic route object creation upon ROA generation starting on 4 November 2024 - more details available in the attached announcement. FYI, /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <info(a)arin.net> Subject: [arin-announce] Reminder - Automatic Creation of Managed IRR Route Objects upon RPKI ROA Generation Coming Soon Date: September 4, 2024 at 11:52:16 AM EDT To: <arin-announce(a)arin.net> In the software release scheduled for 4 November, ARIN will implement new features in ARIN Online that will provide tighter integration of ARIN’s Resource Public Key Infrastructure (RPKI) and Internet Routing Registry (IRR) routing security services. These improvements are informed by the community consultation that closed on 20 September 2023. Based on feedback received from our community during the consultation, ARIN plans to deploy the following features in ARIN Online and in our Application Programming Interface (API) for Hosted RPKI: 1. When a Route Origin Authorization (ROA) is generated, an auto-managed IRR route object will be created based on the contents of the ROA. This feature will be on by default but can be disabled by user action at the Org level. Additionally, a user can opt out of creating an auto-managed IRR route object upon each instance of ROA generation. All auto-managed IRR Route Objects will be identified as such in a remark field. 2. Auto-managed route objects resulting from ROA generation will use the prefix entry only and not take the maxLength value into consideration (using the least specific match). At ROA generation, the user will have the option to replace any existing, matching, and unmanaged route objects with an auto-managed route object. Users may manually create longer match IRR objects, but these manually created objects will not be auto managed. 3. Deleting a ROA will remove associated auto-managed IRR route objects. A user can opt out of removing auto-managed IRR route objects upon each instance of ROA deletion. If a user chooses to not delete an auto-managed IRR route object, the remarks field will be updated to reflect that the IRR route object is no longer auto-managed. Users maintain the ability to create, modify, or delete all IRR route objects through the Manage IRR page in ARIN Online. 4. ARIN Online users will have the option to selectively create auto-managed IRR route objects based on the Org’s existing ROAs in ARIN’s RPKI repository. The Reg-RWS API will be updated to reflect the capabilities as described in items one through three above. If you have questions about these upcoming features, please contact us by emailing routing.security(a)arin.net. Regards, Brad Gorman Senior Product Owner, Routing Security American Registry for Internet Numbers (ARIN) _______________________________________________ ARIN-Announce

REMINDER: Call for Participation -- ICANN81 DNSSEC and Security Workshop
by Jacques Latour 04 Sep '24

04 Sep '24

Hi all! We still have a few openings in our schedule. Thanks, Jacques Call for Participation -- ICANN DNSSEC and Security Workshop for ICANN Annual General Meeting In cooperation with the ICANN Security and Stability Advisory Committee (SSAC), we are planning a DNSSEC and Security Workshop for the ICANN81 Annual General Meeting being held as a hybrid meeting from 09-14 November 2024 in Istanbul, Türkiyea in the Turkey Time TRT- (UTC +3). This workshop date will be determined once ICANN creates a block schedule for us to follow; then we will be able to request a day and time. The DNSSEC and Security Workshop has been a part of ICANN meetings for several years and has provided a forum for both experienced and new people to meet, present and discuss current and future DNSSEC deployments. For reference, the most recent session was held at the ICANN80 The Policy Forum on Monday, 10 June 2024. The presentations and transcripts are available at: https://icann80.sched.com/<https://urldefense.com/v3/__https:/icann80.sched.com/__;!!PtGJab4!7Vwf_nce_…>. The DNSSEC Workshop Program Committee is developing a program for the upcoming meeting. Proposals will be considered for the following topic areas and included if space permits. In addition, we welcome suggestions for additional topics either for inclusion in the ICANN78 workshop, or for consideration for future workshops. 1. Global DNSSEC Activities Panel For this panel, we are seeking participation from those who have been involved in DNSSEC deployment as well as from those who have not deployed DNSSEC but who have a keen interest in the challenges and benefits of deployment, including Root Key Signing Key (KSK) Rollover activities and plans. 2. DNSSEC Best Practice Now that DNSSEC has become an operational norm for many registries, registrars, and ISPs, what have we learned about how we manage DNSSEC? * Do you still submit/accept DS records with Digest Type 1? * What is the best practice around key roll-overs? * What about Algorithm roll-overs? * Do you use and support DNSKEY Algorithms 13-16? * How often do you review your disaster recovery procedures? * Is there operational familiarity within your customer support teams? * What operational statistics have been gathered about DNSSEC? * Are there experiences being documented in the form of best practices, or something similar, for transfer of signed zones? Activities and issues related to DNSSEC in the DNS Root Zone are also desired. 3. DNSSEC Deployment Challenges The program committee is seeking input from those that are interested in implementation of DNSSEC but have general or particular concerns with DNSSEC. In particular, we are seeking input from individuals that would be willing to participate in a panel that would discuss questions of the following nature: * Are there any policies directly or indirectly impeding your DNSSEC deployment? (RRR model, CDS/CDNSKEY automation) * What are your most significant concerns with DNSSEC, e.g., complexity, training, implementation, operation or something else? * What do you expect DNSSEC to do for you and what doesn't it do? * What do you see as the most important trade-offs with respect to doing or not doing DNSSEC? 4. Security Panel The program committee is looking for presentations on DNS, DNSSEC, routing and other topics that could impact the security and/or stability of the Internet. We are looking for presentations that cover implementation issues, challenges, opportunities and best practices for: * Emerging threats that could impact the security and/or stability of the Internet * DoH and DoT * RPKI (Resource Public Key Infrastructure) * BGP routing & secure implementations * MANRS ( Mutually Agreed Norms for Routing Security) * Browser security - DNS, DNSSEC, DoH * EMAIL & DNS related security - DMARC, DKIM, TLSA, etc... If you are interested in participating, please send a brief (1-3 sentence) description of your proposed presentation to dnssec-security-workshop(a)icann.org<mailto:dnssec-security-workshop@icann.org> by Friday, 13 September 2024. Thank you, Kim and Kathy On behalf of the DNSSEC Workshop Program Committee: Gautam Akiwate, Stanford University Steve Crocker, Edgemoor Research Institute Mark Elkins, DNS/ZARC Jacques Latour, .CA Ram Mohan, Identity Digital Russ Mundy, Tislabs Yoshiro Yoneya Dan York, Internet Society

Survey for operators on IPv6 Extension Headers
by Justin Iurman 04 Sep '24

04 Sep '24

Hi NANOG, TL;DR We're still trying to collect more responses from operators, please take a look at the survey [1]. This survey is anonymous (you and your responses), does not require login, and is quite short. On behalf of the University of Liege (Belgium), we've been doing measurements on IPv6 Extension Headers over the last two/three years. More specifically, we're trying to evaluate how they are processed by routers along the path, and so from the edge. Now, we would like to compare our observations with the reality of operators. For that, we propose this very short survey [1] to operators and would really appreciate if you could complete it. Note that we guarantee anonymity of your answers by not sharing any data. Looking forward to your input. Thanks, Justin [1] https://docs.google.com/forms/d/1SqPjLFe0TrWGJHqbBLZsrobiss1s3VR4Q3kbQ3ro4tk

AT&T/Cingular Wireless Switching Contact
by Erik Ogren 30 Aug '24

30 Aug '24

We're having trouble with customers on AT&T/Cingular Wireless SPID 6214 calling into numbers that have ported into us that have our LRN. We had a similar issue in July that resolved itself after several weeks, but it has started back up again. Native/non-ported numbers of ours can be called just fine but not any that have ported into us that have our LRN. Was wondering if anybody from AT&T/Cingular Wireless SPID 6214 monitors this list and can contact me off-list or point me in the right direction for further details so we can hopefully troubleshoot and resolve these issues between us.
