Re: Help with removing DNS shinkhole FP from Charter/Spectrum
by Mel Beckman 22 Apr '24

22 Apr '24

I notice from MXToolbox.com that your domain’s IP address is on the UCEPROTECTL3 blacklist. This is a notoriously evil blacklist that charges people for removal. This may be why Spectrum is blackholing your domain. Most respectable ISPs won’t use it. But Spectrum… There is no delisting procedure without making a “donation” to the UCEPROTECT3 black sparrow account. They’re famous for blacklisting large swaths of IP addresses that catch up innocent parties that have never spammed a flea. -mel On Apr 22, 2024, at 4:51 AM, Validin Axon <axon(a)validin.com> wrote: Looking for some help/advice. Spectrum is sinkholing my company's domain, validin[.]com, to 127.0.0.54. The sinkhole responses come from their recursive DNS servers, 209.18.47.61 and 209.18.47.62, which are defaults for and in use by many of their customers and are only reachable from within the Spectrum network. I've had 4 people over the last week (think: customers, prospects, etc) who use Charter/Spectrum tell me that they have difficulty accessing my website as a result of this sinkhole behavior. This behavior is causing reputational harm to my company. I've personally confirmed this behavior from the Spectrum network (I am also a customer) using dig to test their DNS servers: ``` $ dig +short @209.18.47.61 validin.com<http://validin.com> 127.0.0.54 $ dig +short @209.18.47.62 validin.com<http://validin.com> 127.0.0.54 ``` Using Cloudflare/Google/etc works correctly: ``` $ dig +short @1.1.1.1<http://1.1.1.1> validin.com<http://validin.com> 137.184.54.107 157.245.112.183 $ dig +short @8.8.8.8<http://8.8.8.8> validin.com<http://validin.com> 157.245.112.183 137.184.54.107 ``` I suspect my domain was blocklisted last year when a threat researcher included my domain name in a blog post about a threat they were investigating and cited my company as the source for their data. Someone scraped that post, and my company's domain was accidentally added to two Alient Vault OTX pulses and at least one collection on Virus Total. I removed the domain via false positive reporting from everything I could. However, it appears that being added to Spectrum's DNS sinkhole list is effectively permanent and there's no clear path for false positive remediation. I've tried the official Spectrum support lines for months to no avail, and recently tried reaching out on Twitter, but have had no success there either. I'm clearly not able to find the right people through these routes, as none of the people I reach understand the difference between a DNS sinkhole and an IP block list and don't appear to be aware that DNS blocklisting is a separate behavior from their opt-in content filtering via Security Shield. So, if someone could please help me find the team or individual responsible for Spectrum's DNS sinkhole behavior, I would be exceptionally grateful. :-) As I mentioned, this is causing reputation harm, so switching my own DNS servers is not sufficient. People who need to reach me, can't. So, I would appreciate any other help or advice you have, Kenneth

When I worked in Malaysia back in the day (2007 - 2012), WAN-PHY was generally asked for for 10G services, until about 2010; when folk started to choose LAN-PHY. The reason, back then, was to get that extra 1% of pipe bandwidth :-). Oh I don't think OTN or WAN-PHY have any large deployment future, the cheapest option is 'good enough' and whatever value you could extract from OTN or WAN-PHY, will be difficult to capitalise, people usually don't even capitalise the capabilities they already pay for in the cheaper technologies. Of course WAN-PHY is dead post 10GE, a big reason for it to exist was very old optical systems which simply could not regenerate ethernet framing, not any features or functional benefits. -- ++ytti

constant FEC errors juniper mpc10e 400g

We recently added MPC10E-15C-MRATE cards to our MX960's to upgrade our core to 400g. During initial testing of the 400g interface (400GBASE-FR4), I see constant FEC errors. FEC is new to me. Anyone know why this is occurring? Shown below, is an interface with no traffic, but seeing constant FEC errors.

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
