Need your advice for my BGP Tool
by bogdancyber 31 Jan '26

31 Jan '26

Hello! My name is Bogdan Mihai, I'm 21 yr old from Romania. I recently invented something a little more abstract for BGP security, and I'm almost sure that there is nothing similar. I wasn't inspired by anything when I created this, it was a purely random idea that came to my mind. I'm not even an expert in this field, but from the beginning I saw security from a different angle than the others. I made a tool that basically builds a map of risk areas globally, areas where if someone were to try a hijacking attack, that attack would be successful. This idea came to me when I realized that BGP security is still a big problem. RPKI adoption is still slow. And the problem is that today's security in BGP is more reactive, it comes into play only after the attack is detected and damage is done. So I leave you here the link to the zenodo site where I posted my invention. https://zenodo.org/records/18421580 What I ask of you, and extremely important, is not to analyze every file there, but at least the product overview to understand the idea and tell me who this would be useful to, which company or organization. I know that maybe not everything is perfect there, I'm no expert, but I want to know if this idea really has value. Someone said this (You will probably have the same question): "I have to admit that I haven't read all the files, but from the summary, my first question was "how can anyone benefit from this information?" You wouldn't block traffic from a particular AS just for its safety, just like you wouldn't stop driving just because there are bad drivers around. It seems to me that this could be a research topic to raise awareness of the problems and that's it." And I answered: "Correct — this system is not intended to directly block ASNs. It is a risk intelligence tool, showing where there is real potential for abuse and impact. Think of it as: - city crime maps - seismic risk maps - financial fraud maps No one is "blocking the city" or seismic zones, but everyone uses these maps for preventive decisions and prioritization. In the same way, our tool helps operators and security teams decide where to apply controls, strict ROV or additional monitoring, before an incident occurs." I'm very confused and sad because I worked on this but I don't know who it would be of value to or if it even has any value. I appreciate every opinion.

RPKI's 2025 Year in Review
by Job Snijders 22 Jan '26

22 Jan '26

Dear all, Happy new year! Wanna know how RPKI evolved throughout 2025? Read on! :) In this memo I'll share some RPKI statistics, summarize highlights from the IETF Standards Development process, and reflect on emerging trends. Year to Year Growth of the distributed RPKI database =============================================================== A straight-forward method to compare 2024 and 2025 is to look at the absolute numbers. The below table was constructed using data collected by RPKIViews.org between January 1st, 2025 and December 31st, 2025 with the ARIN, AfriNIC, APNIC, LACNIC, and RIPE NCC Trust Anchors. EOY 2024 / EOY 2025 Snapshot differences: ----------------------------------------- 2024-12-31 2025-12-31 ( diff) Total validated cache size (KB): 767,245 923,058 (+ 20%) Total number of files (object count): 415,384 493,707 (+ 19%) Wall time validation run (seconds): 46 35 (- 23%) Wall time without outliner CA (seconds): 26 33 (+ 27%) Publication servers (FQDNs): 53 60 (+ 13%) Certification authorities: 44,935 49,721 (+ 11%) Route Origin Authorizations (ROAs): 280,692 344,209 (+ 23%) Uniq Validated ROA Payloads: 639,900 787,737 (+ 23%) Average ROAIPAddresses per ROA: 2.3 1.8 (- 22%) Unique origin ASNs in ROAs: 47,282 52,661 (+ 11%) IPv4 addresses covered: 2,726,513,768 2,783,187,105 (+ 2%) Uniq IPv4 addresses covered: 1,658,281,248 1,818,913,944 (+ 10%) IPv6 addresses covered: 17,392 * 10^30 18,684 * 10^30 (+ 7%) Uniq IPv6 addresses covered: 15,139 * 10^30 16,384 * 10^30 (+ 8%) Unique ASPA Customer ASIDs: 87 556 (+539%) The number of IP addresses covered by RPKI ROAs grew by 10%. This is similar to last year's report. However, ASPA object count absolutely skyrocketed in 2025! The "Uniq ASPA Customer ASIDs" field is a simple gauge counter for global ASPA deployment on the signer side. At the moment of writing, for about 0.5% of Autonomous Systems in the Internet global routing system an ASPA record is published. That's a very interesting development. The ability to publish ASPA objects became readily available [4] in the RIPE NCC region in 2025, and as of January 2026 also fully available through ARIN Online [5]. The "Wall time validation run (seconds)" metric is produced by revalidating the data contained in the two snapshots multiple times in a benchmark using the same modern multi-threaded RPKI cache implementation on the same 4 CPU core machine, without performing any network operations (i.e. offline validation mode). This metric relates to the hypothesis that as the RPKI grows (in size and number of objects), without also improving efficiency (information density), the overall processing time to validate the complete dataset will increase. This year's benchmark environment: Rpki-client 9.7, OpenSSL 3.5.4, Debian 13, on Intel Xeon. WITH EVERY RPKI CA, FIRST 2024 THEN 2025: $ hyperfine -w2 'rpki-client -p4 -P 1735689171 -n -d rpki-20241231T235251Z/data /tmp' Time (mean ± σ): 46.514 s ± 0.172 s [User: 173.345 s, System: 5.264 s] Range (min … max): 46.257 s … 46.756 s 10 runs $ hyperfine -w2 'rpki-client -p4 -P 1767225374 -n -d rpki-20251231T235614Z/data /tmp' Time (mean ± σ): 35.046 s ± 0.206 s [User: 125.092 s, System: 5.894 s] Range (min … max): 34.756 s … 35.444 s 10 runs FIRST 2024 THEN 2025, WITHOUT THE OUTLINER CA: 20241231T235251Z: Time (mean ± σ): 26.257 s ± 0.152 s [User: 92.878 s, System: 4.590 s] Range (min … max): 26.069 s … 26.485 s 10 runs 20251231T235614Z: Time (mean ± σ): 32.903 s ± 0.143 s [User: 117.059 s, System: 5.444 s] Range (min … max): 32.635 s … 33.127 s 10 runs This year the "wall time" metric _seemingly_ deflated... but, unfortunately, further sleuthing shows that the 2024 numbers were heavily skewed by the products issued by a specific large CA under ARIN, an outliner so to speak. In the 2024 snapshot that one CA had 50,125 Manifest entries and 15,944 CRL entries, while in the 2025 snapshot the same CA had 48,896 Manifest entries and only 33 CRL entries. The key observation here is that the impact of large CRLs becomes more pronounced with longer Manifests. In conclusion and discounting the products of that one outliner CA, overall processing time of the RPKI increased by 25%. [ Note: the wall time metric is not comparable between successive annual reports (for example, next year I might use a different computer, or use a different validator implementation) - but within the context of a single annual report the comparison between the snapshots is apples to apples! ] The "Average ROAIPAddresses per ROA" metric shows how many IP prefixes, on average, are contained within a single ROA object. The higher the number of ROAIPAddresses per ROA is, the higher computational efficiency likely is to be. "Efficiency" in this context is viewed as how many ROAIPAddress entries are packed together and signed with a single EE certificate. A higher number means more efficiency (and less RP bandwidth consumption) The RIPE NCC hosted CA system yields 6.6 prefixes per ROA, while the current ARIN and LACNIC approach result in only 1.1 and 1.3 prefixes per ROA, respectively (almost the worst possible case). APNIC and its community lead in efficiency with 8.2 per ROA. The impact that CA implementation choices have on the RPKI's scalability remains an area of concern: large CA operators (such as the RIRs) need to take special care when deciding on parameters such as ROAIPAddress packing and certificate validity periods, in order to curb uneconomical Manifest & CRL growth. Issuing RPKI objects aiming for high information density helps improve predictable delivery trajectories towards relying parties. Statistics on accumulating counters throughout the year: -------------------------------------------------------- The following statistics were produced using the RPKIViews 2024 Amalgamation [6] and RPKIViews 2025 Amalgamation [7] datasets. I believe these datasets to be a near complete collection of all signed RPKI data produced in those years. Almost every ROA! The objects in the Zenodo hosted archives can be inspected with "rpki-client -jf" (filemode). 2024 2025 Number of Rpkiviews snapshots produced: 64,923 90,523 (+ 39%) Newly discovered RPKI objects: 56,586,149 61,524,413 (+ 9%) Avg number of new objects per second: 1.79 1.98 (+ 10%) Median object size (bytes): 1,924 1,924 ( -) Mean object size (bytes): 2,193 2,531 (+ 15%) Cumulative size of all objects (KB): 121,211,067 152,094,584 (+ 25%) The above numbers can be used to better understand RPKI transport protocol efficiency. More on that next year! IETF SIDROPS - Working Group developments ========================================= Some fun updates from the IETF working group responsible for development and maintenance of the RPKI technology stack... *** SIDROPS ***. This RPKI-focused design & implementation group now operates with a new charter. The most significant change in modus operandi being that RFC publication now requires multiple implementations to exist and interoperate. Read the full charter here: https://datatracker.ietf.org/wg/sidrops/about/ ASPA - where we at? ------------------- Close to Working Group Last call! Depending our luck this might mean the specifications are published in late 2026. Word on the streets is that various commercial-off-the-shelf/hardware vendors are working on ASPA implementations, and a number of BGP open source projects already made ASPA verification implementations available to the wider public. Other (New) Work in SIDROPS --------------------------- 1/ A new scalable data synchronisation protocol called Erik Synchronisation is in the works. It is a HTTP-based protocol using Merkle trees, a content-addressable naming scheme, and concurrency control using monotonically increasing sequence numbers. https://datatracker.ietf.org/doc/html/draft-ietf-sidrops-rpki-erik-protocol 2/ What MRT Tabledumps meant for researching BGP, is what CCR is intended to be for the RPKI. CCR (Canonical Cache Representation) is a new small and efficient binary file format to record validation outcomes and hash markers. https://datatracker.ietf.org/doc/html/draft-ietf-sidrops-rpki-ccr SIDROPS Finished work --------------------- One new clarification RFC was published: * RFC 9829 - Handling of Resource Public Key Infrastructure (RPKI) Certificate Revocation List (CRL) Number Extensions https://www.rfc-editor.org/rfc/rfc9829.html Small Point On Housekeeping: ============================ The RPKIViews archive data collection approach and structure were revised at the start of 2026. A number of rpkiviews gatherer nodes now use a Tar+Zstandard spooling system to store raw data and associated snapshots in Canonical Cache Representation format. The changes in how RPKIviews data is stored should have a positive effect, meaning more snapshots can be gathered per hour while at the same time consuming less disk storage space than previously. I'm curious to see what this increase in data resolution might show us next year! Final words =============================================================== The RPKI remains an important tool in the toolbox to identify & prevent routing incidents. Deployment of RPKI allows operators to improve network reliability by strengthening the security and integrity of their interconnection with the global Internet routing system. The system is working pretty good and will continue to serve us well if special care is taken to continually monitor and optimize the RPKI's data packing practises & delivery methods.

Techniques to influence inbound (download) traffic across multiple IXPs with /24 prefixes
by Salvador Bertenbreiter 08 Jan '26

08 Jan '26

Hi everyone, Hope you’re doing well. I’d like to ask how you approach inbound traffic engineering (download traffic) when you’re connected to multiple IXPs (some local, some remote) and you only have small prefixes (e.g., /24), so announcing more/less specifics isn’t really an option. In that scenario, what methods have worked for you besides simple AS-path prepending (e.g., no prepend on local IX, prepend 1 on the closest remote IXP, prepend 2 on the next, etc.)? Thanks in advance for any guidance or real-world examples. -- Salvador

Empty RPKI repositories RFO
by Bart Bakker 08 Jan '26

08 Jan '26

Dear colleagues, On 7 January 2026 at 15:11 UTC, all objects were removed from both our RRDP and rsync RPKI repositories. At 15:20 UTC, the repository state was restored, and all objects were back. At 15:08 UTC, we did a production deployment of our CA software on the first application node. We deploy one node at a time so that we have zero downtime during deployments. We carried out a database DDL change on the table storing published objects, which took roughly 40 seconds to execute. During those 40 seconds, the online node queried the published objects in order to publish them. This transaction had to wait for the table lock held by the DDL change to be released. When the lock was released, PostgreSQL returned zero rows. We learned that this is a known caveat [1]: after rewrite commits, the table will appear empty to concurrent transactions. We will implement circuit breakers between all phases of our publication process to prevent this situation from happening in the future. [1] - https://www.postgresql.org/docs/18/mvcc-caveats.html Apologies for the inconvenience this has caused. Kind regards, Bart Bakker Specialist Software Engineer RIPE NCC
