Announcement of new RIS prototype services
by Oleg Muravskiy 05 Aug '22

05 Aug '22

Dear RIS users, Over the past few months, we have created several prototype services that expose RIS data in different ways. These services provide a REST API, and the data they expose is closer to real-time, as compared to our traditional "bview" and "updates" files. These services are: - Per-peer dumps https://ris.ripe.net/docs/40_Prototypes/10_per_peer_dumps.html - Per-RRC dumps https://ris.ripe.net/docs/40_Prototypes/15_per_rrc_dumps.html - Peer metadata https://ris.ripe.net/docs/40_Prototypes/20_peer_metadata.html Please take a look at the documentation (links provided above), try out these new services, and tell us what we can improve! We would love to hear your feedback. Since we're posting this message across multiple mailing lists, we ask you to please share your feedback on the ris-users(a)ripe.net mailing list, or write to us directly at ris(a)ripe.net rather than on this list. Kind regards, Oleg Muravskiy RIPE NCC

Frequently Asked Questions about 2000::/12 and related routing errors
by Job Snijders 07 Jul '22

07 Jul '22

Dear all, Last night many people received "Resource Certification (RPKI)" alerts, which in turn caused my phone to light up with questions! :-) In the below message I'll attempt to provide an analysis of what happend and answer frequently asked questions. * What happened? * Has this happened before? * Why didn't RPKI Route Origin Validation (ROV) stop this? What happened? ============== As reported in the media (https://twitter.com/DougMadory/status/1544862409336184832) one Internet Service Provider announced to the world - through the BGP protocol - that all Internet Protocol addresses contained within 2000::/12 were reachable via them. This was a routing error, an error condition which triggered various monitoring systems around the globe. Background: The BGP Default-Free Zone is composed of ~ 150,000 IPv6 networks originated from ~ 24,000 Autonomous Systems (ASes). The totality of this is what forms the IPv6 Internet. The majority of these networks have a prefix length in the range of /32 up to /48. Currently the world's largest IPv6 assignments (of which there are very few) are clocking in at /19. So, a /12 ("slash twelve") BGP announcement covers an exceptionally large number of IP addresses! This night's /12 BGP announcement covered such a large block of address space, it happened to overlap with about 21,292 existing networks originated by 3,697 ASes. For roughly 69% (14,695) of those networks RPKI ROAs had been created. About 10% (2,176) of those "RPKI ROA covered existing networks" is IPv6 space managed under the RIPE NCC umbrella. I imagine a few hundred operators received alerts from RIPE NCC with a suggestion to considering creating corresponding ROAs to make the 2000::/12 announcement valid; however no ISP can create such a ROA, because no single ISP is authoritative for the entirety of that block. :) Has this happened before? ========================= Yes. This type of routing error happens almost annually. Some time ago Tom Strickx reported an incident involving 2400::/12, a block which nowadays overlaps with more than 40,000 networks! (source: https://twitter.com/Jerome_UZ/status/1145136294835523584) If my memory serves me right, back in 2016 AS 1299 originated both 2000::/6 and 2000::/12, later that year AS 10026 also originated 2000::/12 for a bit. So... how exactly can this happen? I believe it is a mixture of user-interfaces with really sharp edges and permissive EBGP filters. Many router-to-router linknets are assigned a /127 [RFC 6164] or a /64 [RFC 7421], and loopback addresses generally are assigned a /128 (a single address). It's not hard to imagine that when copy+pasting or typing by hand, an operator fails to input the last digit (respectively a 7 in the case of /127, the 4 in /64, or the 8 in /128), resulting in a configuration with a /12 or a /6 as the prefix length. See these Cisco & Juniper terminal transcript examples for a demonstration of failing to correctly enter the last digit of "2001:67c:208c::/128" : https://chloe.sobornost.net/~job/slash-twelve.txt Why didn't RPKI ROV stop this? ============================== Creating RPKI ROAs and performing Route Origin Validation (ROV) on received BGP route announcements helps protect against mishaps with unauthorized "same-length" and "more-specific" announcements. ROV (by design) does nothing against unauthorized "larger overlapping" route announcements (such as 2000::/12). This is because the Internet's global routing system is based on the Longest Prefix Match (LPM) algorithm (see https://en.wikipedia.org/wiki/Longest_prefix_match) LPM means that as long as your certified address space is in the global routing table, a less-specific announcement (such as 2000::/12) is not very likely to draw IP traffic away from your network. In incidents like these the major impact seems to be that monitoring systems are triggered (which is appropriate!). I suspect there is virtually no impact to business operations (fortunately!). Questions welcome! Kind regards, Job

RPKI Quarterly Planning Q3 2022
by Nathalie Trenaman 29 Jun '22

29 Jun '22

Dear colleagues, The quarterly planning for Q3 2022 for RPKI has now been published: https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan… <https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan…> Recently, we published a page for the different components of RPKI which can be accessed at: https://status.ripe.net <https://status.ripe.net/> We’re still carrying on with the activities started in Q1 2022 such as implementing "Publish in Parent" RFC 8181 support and creating multiple parallel internal test environments for RPKI. We’ll announce here on the list when these have finished. Also, we’re currently starting the process for the purchase of the new HSMs, which we will start to use as soon as we can. The goal of our quarterly planning is to communicate the work we’re doing for the coming months, get your input and start a discussion on other developments we should work on. If you have any comments or questions, we hope you'll discuss with us on the list or, if you prefer, you can always contact the team directly at rpki(a)ripe.net <mailto:rpki@ripe.net> . Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

RPKI Outage on 23 June 2022 from 10:50 UTC - 12:00 UTC
by Stella Vouteva 28 Jun '22

28 Jun '22

Dear colleagues, Yesterday, we performed an upgrade on the Security world software on our RPKI core servers. The upgrade was finished at approximately 08:45 UTC. We tested the upgrade and verified that everything worked before enabling the RPKI dashboard again. At approximately 10:50 UTC, we received an alert from our monitoring that showed an error for both our online Hardware Security Modules (HSMs). While we immediately started the investigation of this alert, we also decided to temporarily stop RPKI Core to keep a consistent state. This also meant that we had to temporarily close down the RPKI Dashboard. At 11:22 UTC we contacted our vendor as we had never seen this behaviour before. A consultant from our vendor advised a reboot of the HSMs, which we performed at 11:55 UTC. After the reboot, the HSMs got back online and we enabled the RPKI Core and RPKI dashboard. It is still unknown whether the upgrade was the direct cause of the errors, as the error was very generic. While we are working on finding the root cause, we still need to reboot systems and HSMs occasionally, which causes unavailability of the RPKI Dashboard for a few minutes and it will take a bit longer than usual for objects to get published in our repository. As soon as we have more information, we will share it here. As a result of this outage, we will speed up the process to replace the online HSMs, which we described in our recent RIPE Labs article <https://labs.ripe.net/author/ties/securing-the-ripe-ncc-trust-anchor/> [0]. Kind regards, Stella Vouteva [0]: https://labs.ripe.net/author/ties/securing-the-ripe-ncc-trust-anchor/

state of RPKI-invalid objects in IRR databases (2022.05.16)
by Job Snijders 16 May '22

16 May '22

Dear all, On the #DENOG IRC channel I was asked for current stats on the number of RPKI-invalid IRR route/route6 objects in various databases as follow-up to a talk at RIPE81 [0]. I figured I should share this with the WG too. Below is a table with today's stats of number of invalid route/route6 objects when one applies the RFC 6811 origin validation algorithm with as input prefix value in the "route:" attribute and the origin AS in the "origin:" attribute. invalids invalids AFRINIC: ipv4: 359 - ipv6: 12 - authoritive ALTDB: ipv4: 1 - ipv6: 191 - note 4 APNIC: ipv4: 21861 - ipv6: 1880 - authoritive ARIN: ipv4: 814 - ipv6: 65 - authoritive BBOI: ipv4: 44 - ipv6: 1 BELL: ipv4: 322 - ipv6: 0 JPIRR: ipv4: 95 - ipv6: 4 LACNIC: ipv4: 0 - ipv6: 0 - authoritive (note 3) LEVEL3: ipv4: 12925 - ipv6: 182 NTTCOM: ipv4: 65513 - ipv6: 730 RADB: ipv4: 208901 - ipv6: 12829 RGNET: ipv4: 2 - ipv6: 0 RIPE: ipv4: 28390 - ipv6: 3518 - authoritive RIPE-NONAUTH: ipv4: 5 - ipv6: 0 - note 5 TC: ipv4: 0 - ipv6: 0 - note 2 Some notes on the above table: 1) ARIN-NONAUTH is not listed, ARIN deprecated this IRR source a month ago [2]. 2) TC achieved a perfect 0/0 score by using the IRRd v4 RPKI integration [3]. 3) LACNIC's IRR service is an information proxy for RPKI ROAs valid under the LACNIC Trust Anchor. This by definition means that all IRR objects in the LACNIC IRR database are RPKI-valid. 4) ALTDB periodically runs a script to delete RPKI-invalid objects 5) RIPE-NONAUTH imposes a two week delay before deleting RPKI-invalid objects, so the 5 IPv4 objects currently marked as invalid with disappear in the next few days, unless the covering RPKI ROAs are withdrawn before the timer expires. The stats are generated by downloading the IRR database dump for each source and running a simple python script [1].

RIPE-84 talk about RIPE RPKI core
by Bart Bakker 11 May '22

11 May '22

Dear Colleagues, Early this year we announced [1] that we published the source code of our trust anchor software. We thought it would be interesting to share how we did this and what influenced certain decisions in the process. So at RIPE-84 we scheduled a talk about this in the Open Source Working Group [2]. Hope to see you there. [1] - https://www.ripe.net/ripe/mail/archives/routing-wg/2022-February/004509.html [2] - https://ripe84.ripe.net/programme/meeting-plan/os-wg/ Kind regards, Bart Bakker Senior Software Engineer RIPE NCC

New on RIPE Labs: Securing the RIPE NCC Trust Anchor
by Alun Davies 09 May '22

09 May '22

Dear colleagues, The RIPE NCC recently migrated one of the Hardware Security Modules (HSMs) they use to handle keys in RPKI. In this new article on RIPE Labs, Ties and the team give a detailed overview of the role HSMs play in the broader RPKI system and talk through the steps they took to carry out the migration: https://labs.ripe.net/author/ties/securing-the-ripe-ncc-trust-anchor/ Best regards, Alun Davies RIPE Labs Editor RIPE NCC

Follow up: RIPE NCC Open House - RPKI Data
by Nathalie Trenaman 09 May '22

09 May '22

Dear colleagues, Last week, on Wednesday 4 May 2022, 14:00 UTC, we held a RIPE NCC Open House on the topic of RPKI Data. You can find the recording here: https://www.ripe.net/participate/meetings/open-house/ripe-ncc-open-house-rp… <https://www.ripe.net/participate/meetings/open-house/ripe-ncc-open-house-rp…> Thank you to all who participated, I thought it was a useful session and I enjoyed the discussion and feedback we received. During the session I promised to send an e-mail to this list with a summary of all data and visualisations we currently have public for RPKI: Visualisations: https://certification-stats.ripe.net/ <https://certification-stats.ripe.net/> -Generated from the RIR Trust Anchor Statistics https://ftp.ripe.net/rpki/ <https://ftp.ripe.net/rpki/> https://lirportal.ripe.net/certification/content/static/statistics/world-ro… <https://lirportal.ripe.net/certification/content/static/statistics/world-ro…> -Generated from "delegated stats” in combination with BGP data from RIS -No IPv6 Data: https://ftp.ripe.net/rpki/ <https://ftp.ripe.net/rpki/> -Documented on https://github.com/RIPE-NCC/internet-dataset-descriptions/blob/main/rpki-re… <https://github.com/RIPE-NCC/internet-dataset-descriptions/blob/main/rpki-re…> -Daily data per Trust Anchor per 2011 Public tools: https://rpki-validator.ripe.net/ui/ <https://rpki-validator.ripe.net/ui/> -User interface for Relying Party software https://stat.ripe.net/widget/rpki-by-trust-anchor <https://stat.ripe.net/widget/rpki-by-trust-anchor> -Generated from https://ftp.ripe.net/rpki/ <https://ftp.ripe.net/rpki/> https://stat.ripe.net/app/use-cases/asn/rpki-check/S1_3333_C16e <https://stat.ripe.net/app/use-cases/asn/rpki-check/S1_3333_C16e> (example) -Shows the RPKI validity state for a combination of prefix and Autonomous System. -Generated from https://rpki-validator.ripe.net/ui/ <https://rpki-validator.ripe.net/ui/> https://stat.ripe.net/docs/02.data-api/rpki-history.html <https://stat.ripe.net/docs/02.data-api/rpki-history.html> -API call returns a timeseries with the count of VRPs (Validated ROA Payload) for the requested resource. -Generated from https://ftp.ripe.net/rpki/ <https://ftp.ripe.net/rpki/> My key take aways from the session: -Ruediger Volk asked for an inventory of our current data, visualisations and tools. I started by this e-mail to the Working Group and I’m still considering how to make them easier to find on our website. -Randy Bush noted that experiments will/might pollute our data. Ties suggested to add known experiments to the GitHub dataset description. -Mingwei Zhang mentioned that he is currently working with Emile Aben and Agustin Formoso on “when did a VRP appear/disappear” feature for RIPEstat. This will be a very valuable addition for trouble shooting. -John Kristoff would like to see statistics on the time it takes from the moment someone hits “submit” in the LIR portal for a ROA, to the moment the VRP is visible in the repository and when it is seen picked up by routers. -Job Snijders mentioned that it would be beneficial to have ftp.ripe.net/rpki <http://ftp.ripe.net/rpki> data available as rsync://ftp.ripe.net/rpki <rsync://ftp.ripe.net/rpki> -Amreesh Phokeer suggested a more granular data set for Trust Anchor data. This is currently a daily dump. We are interested to hear how granular would be useful. Also Amreesh would be interested in statistics about revoked ROAs. -Ruediger Volk added that he would be interested in data that shows how frequent CRLs are used. Job Snijders provided insight in his mail to the WG: https://www.ripe.net/ripe/mail/archives/routing-wg/2022-May/004566.html <https://www.ripe.net/ripe/mail/archives/routing-wg/2022-May/004566.html> -Sacha mentioned that it would be useful to have a tool that would show how a ROA would impact a route, without actually creating that ROA, or for a prefix that you don’t have holdership of. -Nathalie said that she would like to get rid of the world map, as it is now well-known and does not include IPv6. A better alternative, that includes IPv6 can be found on: https://rpki-maps.nlnetlabs.nl/ui/world.html <https://rpki-maps.nlnetlabs.nl/ui/world.html> We’re looking into all your suggestions and where possible implement them. Stay tuned :) If I missed something, or if you want to share your thoughts, have suggestions, please send an e-mail to the list or directly to us on rpki(a)ripe.net <mailto:rpki@ripe.net> Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

follow-up on RPKI open house: are CRLs used?
by Job Snijders 04 May '22

04 May '22

Hi, A question was raised during today's RPKI Data Open House: "are CRLs used?" Just now I ran some statistics on today's RPKI state using the 5 RIR TALs: * There are 30,914 CRL files. * In totality, these 30K CRLs list revocations for 331,637 serials. * 5,369 CRL files don't list revoked serials (at this point in time). * On average, the non-empty CRLs list 12 revoked certs. Further analysis can be performed using this JSON representation of the global RPKI state: https://console.rpki-client.org/dump.json (174 megabyte) https://console.rpki-client.org/dump.json.gz (38 megabyte) The dump.json file is regenerated a few times a day. Kind regards, Job
