Upcoming LACNIC RPKI Migration
by Carlos Martinez-Cagnazzo 16 Apr '24

16 Apr '24

Hello all, On April 15th, 2024 starting approximately at 9.30am UTC-3 LACNIC will be migrating from our current legacy RPKI CA system to a new Krill-based RPKI core. In most cases no action will be required on your part (see below for some special cases). What follows is a list of events that will take place at the mentioned time and that may be of interest to you. * Our TAL file won't change at this time. There is no need to change anything in your current RP configuration. * Our RTA certificate, while keeping the old key will point to a new manifest. >From the outside, what RPs will see is the following sequence of events: * At some time T0 all our current servers (both RRDP and rsync) will be shut down, returning "connection refused '' for both http and rsync. * New values for the DNS records will be published (same names, different IPs). * At approximately T0+30min the servers listening on the new IPs will be started and will start serving the repository as produced by the new Krill-based system. * When they first connect, RPs will see a new RRDP session and will take it from there. We have tested this migration flow using a set of docker containers plus a DNS server container using dnsmasq server that allows us to modify records on the fly. In all the cases we tested this flow works just fine. We have tested this migration flow with the following RPs: * rpki-client from “latest” all the way back to 8.2. * routinator from “latest” all the way back to 0.8. * fort from “latest” all the way back to 1.5.0. What we have not tested: * RIPE rpki validator: it’s been deprecated for three years. You shouldn’t be running this and you know it :-) In any case, it should work. * OctoRPKI: also recently deprecated. * Rpki-prover. * RIPSTR. All of the above should work. However bear in mind the following: If you are running any of the above and you notice issues, just clear the local cache, launch a clean instance of your RP and you should be fine. We have set up a specific email inbox for this migration work: rpki-migracion(a)lacnic.net. It will be closely monitored during April 15 and the following days. It will be phased out once we are confident all issues that may arise have been addressed. For those interested, the new servers are already online and can be used to validate. These can be reached at: * lb-us-mia.rrdp.lacnic.net * lb-us-southeast.rrdp.lacnic.net * lb-br-gru.rrdp.lacnic.net Don’t expect to see the exact same VRPs as you see now on our current production server as minor differences are expected. Don’t hardcode this either, as during the migration “rrdp.lacnic.net” will be made to point to these servers and eventually these names may change and/or new ones may be added. Thank you all! /Carlos

MTA-STS operational practice survey
by Chung, Tijay 16 Apr '24

16 Apr '24

Greetings, Together with researchers from Virginia Tech and Max-Planck-Institut für Informatik, we would like to understand the general trends, operational practices, and challenges of MTA-STS protocol from the mail operators' point of view. It takes around 5-6 minutes and you can stop participating in the study at any time; we would truly appreciate your participation. We do not collect any personal information and all answers except the first couple of consent questions are optional. If you do not want to answer any questions, please just leave the field blank. https://www.surveymonkey.com/r/JKWNDSN Please do not hesitate to email me if you have questions or comments. Also, please excuse us if you have received this email from different mailing lists. Thank you. Thanks, Taejoong "Tijay" Chung, Assistant Professor Virginia Tech | Computer Science 220 Gilbert Street, RM 4303 Blacksburg, VA 24060 (540) 231-0667| tijay(a)vt.edu<mailto:tijay@vt.edu>

2600:: No longer pings
by Ben Cartwright-Cox 14 Apr '24

14 Apr '24

It appears that 2600:: no longer responds to ICMP. $ mtr -rwc 1 2600:: Start: 2024-04-06T10:53:41+0100 HOST: metropolis Loss% 1.|-- lcy02.flat.b621.net 0.0% [...] 6.|-- ldn-b4-link.ip.twelve99.net 0.0% 7.|-- ldn-bb1-v6.ip.twelve99.net 0.0% 8.|-- nyk-bb2-v6.ip.twelve99.net 0.0% 9.|-- ??? 100.0 10.|-- sprint-ic301620-nyk-b5.ip.twelve99-cust.net 0.0% 11.|-- ??? 100.0 This seems to have happened around Friday 5th 13:40 UTC. 2600::, a IP address owned by the Sprint network (Now since acquired by Cogent Communications) is a common (at least in my circles) IPv6 testing address, in a similar way that 8.8.8.8 or 1.1.1.1 is for a quick address to remember that always pings, when such a address is so easy to remember, you sometimes cannot help it becoming a "core project" :) ( https://xkcd.com/1361/ ) 2600:: is also used to be the address of sprint.net, now sprint.net has no v6. This is sad, and I would either propose that Cogent/Sprint (I assume 2600:: is under the ownership of Cogent now) revive this address as it's a very helpful testing address that is burned into the minds of many. Or at the very least, I'm more than willing to tank the effort of responding to ICMP!

PRIX update
by Mehmet 13 Apr '24

13 Apr '24

Hello NANOG Little bit less than 19 years ago when PRIX was launched I had a dream to connect many ISPs in the island. during last 19 years several attempts were made to relaunch an IX but finally last three years a small group of volunteers have really helped PRIX to be come a reality not an IX with PowerPoint and no traffic. You can hear the story from those who have significantly helped from project here https://www.youtube.com/live/kCp4kK-mavU?si=N82CGRSatdzrmX2H This week there is Global Peering Forum in Puerto Rico, and I as one of the old time nanoger + local(i dont live here anymore but, you know what i mean want to welcome and send this update about PRIX https://www.puertoricoix.net has broken traffic record 30Gbps last week and with some more caches in the process of being enabled as well as some key peers (listed on the website), next goal is 100G and this can be achieved with those of you who has an ability to help deploy more caches in Puerto Rico! 🇵🇷 I want to take a moment thank Jeff, Ivan, and Gino for all the hard work behind. If you are attending GPF this week, let’s talk and see what else we can do to improve internet in Puerto Rico and Caribbean! Any questions related to PRIX feel free to contact me offlist Mehmet Note: all links below are broken 😞 PRIX - Puerto RIco Internet Exchange - *From:* Mehmet Akcin - *Date:* Tue Sep 27 12:50:12 2005 ------------------------------ Hi, I'd like to speak with people who were / are working in IX points and/or have knowledge about the infrastructure of IX points. We , a small group of researchers , have started a Project called Prix [http://prix.uprr.pr ] which has the intentions of creating a large table for those who would like to sit down, in other terms an internet exchange point where all the participants can peer. Our main goal is to improve the existing connectivity between the major backbone providers and improve the connectivity between them with peering locally instead of peering somewhere in the states, which is couple of thousands miles far from Puerto Rico. We believe improving the network connectivity of the island will definately led those who live in Puerto Rico to think of using VoIP technologies more often. We, myself and a friend of mine who is also participating in this project, will be participating in NANOG and hopefully can meet with those who has experience in order to get recommendations about hardware/software and policies. Thank you Mehmet Akcin, PRIX

Anyone got a contact at OpenAI. They have a spider problem.
by John Levine 12 Apr '24

12 Apr '24

As I think I have mentioned before, I have the world's lamest content farm at https://www.web.sp.am/. Click on a link or two and you'll get the idea. Unfortunately, GPTBot has found it and has not gotten the idea. It has fetched over 3 million pages today. Before someone tells me to fix my robots.txt, this is a content farm so rather than being one web site with 6,859,000,000 pages, it is 6,859,000,000 web sites each with one page. Of those 3 million page fetches, 1.8 million were for robots.txt. It's not like it's hard to figure out what's going on since the pages all look nearly the same, and they're all on the same IP address with the same wildcard SSL certificate. Amazon's spider got stuck there a month or two ago but fortunately I was able to find someone to pass the word and it stopped. Got any contacts at OpenAI? R's, John PS: If you were wondering what they're using to train GPT-5, well, now you know.

Attn Access ISPs - FCC BB Labels (machine-readable standards)
by Livingood, Jason 12 Apr '24

12 Apr '24

Yesterday the FCC broadband label order is in effect – so all ISPs need to publish them. Oct 10, 2024 is the deadline to produce machine-readable BB labels. I have kicked off an effort via the BITAG to standardize the format of these labels. See https://github.com/jlivingood/Broadband-Labels<https://urldefense.com/v3/__https:/github.com/jlivingood/Broadband-Labels__…> for some initial ideas. If you’d like to participate – because you are an ISP publishing labels or an org/researcher that will be importing/consuming/comparing labels – you may wish to participate. There’s no fee or docs to sign to do so, and your participation does noy convey endorsement of the final work product. IF INTERESTED – email me off-list and I will provide details. Thanks! Jason
