TDM Voice Issue
by Mike Hammett 30 Aug '25

30 Aug '25

Normally, I'd post on VoiceOps (and I did), but that list is currently quite neutered. Frontier wholesale support was of little help. Can anyone help in a CLLI code lookup to see who that ID corresponds to? I have a circuit ID, but I only know my CLLI and Frontier's CLLI code, not who the other entity is. I also see a "Carrier Identification Parameter: 5483" if that means anything to anyone. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

IPv4 Games
by Justine Tunney 29 Aug '25

29 Aug '25

I operate an online service at https://ipv4.games/ that invites people to send http requests to my web server from a lot of different IP addresses. In order to claim an IP, you need to successfully make a tcp three-way handshake with a VM on Google's network. Somehow a player in Europe named femboy.cat has successfully managed to claim 20 million IPs, which is 9% of all IPv4 hosts according to Censys. Does anyone have any idea how they're doing it? Would anyone here be willing to be their North American rival?

Link-state EGP
by Saku Ytti 28 Aug '25

28 Aug '25

The SPF discussion reminded me of a question I've been thinking about. Why do we use distance vector EGP? Why do we advertise prefixes? BGP made sense when we didn't have to worry about degenerates, when the Internet was largely academic. Prefix is configured once to the site where it exists, and no one else does anything, very optimal. But is that sensible today? When we have to also configure the prefix out-of-band locally on every site, potentially 3 times, RPKI (RTR maybe), prefix-list (for BGP) and access-list (for antispoof). So if we discover ASN/Prefix association anyhow out-of-band, why do we need to see +million prefixes in-band? What if EGP would flood link-states? What would we win? What would we lose? Potential wins: - flooded link-states could be signed, so we could verify both AS1->AS2, AS2<-AS1 link-state exists with valid signatures. You couldn't hijack ASN, the entire path could be validated. - initial convergence would be 50-100 times faster - lot less signalling/flapping - loop free alternatives for rapid convergence We could see some problems, for TE reasons I might advertise different prefixes from different sites with the same AS. I'm not sure if that is a legitimate concern, those are niche cases and for those cases we could just register more ASNs and move the ASNs instead of prefixes. But I'm sure there are more obvious weaknesses that don't immediately spring to mind. -- ++ytti

This has never been guaranteed, has always been questionable, and, historically, was actively discouraged, at least by the RIRs (“the Internet does not use geopolitical boundaries for address allocation”, handwaving away the RIR geographical monopolies). Huh? It wasn't that many years ago, ARIN considered "out of region" utilized IP space to not qualify as "utilized" for purposes of qualifying for additional allocations by showing your existing allocations were sufficiently utilized. Though that issue is relatively moot at this point, that policy did eventually change. The problem, as I think you pointed out earlier, is that various parties, for good or ill, need there to be an <IP,geo> binding, even if it doesn’t really exist, so using what information they have, they make it up as they go along. Sometimes (usually) it works. Sometimes, it doesn’t. The crux is that, when it doesn’t, the mechanisms to fix the binding, such as they are, sucks This varies quite a bit from one IP Geo provider to the next. Some are pretty good (have web pages where you can do test queries against their data, will accept your geofeed data if you tell them where to get it, etc.). Others (like Digital Element) seem to be entirely opaque and obtuse. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Blue Stream Fiber, Sr. Neteng | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________ _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/nanog@lists.nanog.org/message/2ELNADG…

Where else do you hangout?
by Mark Prosser 26 Aug '25

26 Aug '25

I was chatting with some industry colleagues recently and I realized that various sectors of our industry are not "online" in the spaces I'm online. Perhaps there was a time when most of us were on mailing lists & IRC, but now the communities seem fragmented and behind walled gardens (Mainly Discord and Slack .. the latter is deleting our messages faster and faster). Personally, I'm subscribed to several discord groups (including NANOG), several slack groups, a few mailing lists, IRC (I'm not on that often these days), one or two Matrix groups, IETF Zulip... This quickly becomes cumbersome and I find myself mainly in Packet Pushers & NAF Slack groups -- while being "reachable" in other places. I feel like I'm missing out on conversations outside of the few bubbles I participate in. Where do you spend most of your time, outside of this mailing list? Why do you like it there? What kind of folks hangout there? Warm regards, -- Mark Prosser // E: mark(a)zealnetworks.ca // W: https://zealnetworks.ca

One would think that if you are in the business of selling data, specifically, location data, that you would have a link on your website for people to contact you in regards to updating that data so that the data you are selling is accurate data. Or do you prefer to sell inaccurate data or do you just not care about the accuracy of your product? Anyways, i’ll get off of my soap box… ***ATTENTION*** Digital Element, Neustar and ipinsight.io folks…. How does one report to you inaccurate geolocation data? Anyone on list that could possibly help a brother out? Thank You, Mike

Having Geo-IP issues in the past week or so? Digital Elements wet the bed…
by Mike Lyon 24 Aug '25

24 Aug '25

If any eyeball networks are having geo-ip issues that started a week or so ago for their customers trying to use HBO, Hulu, Netflix or any others that use Digital Elements for their geo-ip, be sure you make Digital Elements aware. Digital Elements ran a process update last week that screwed up a bunch of netblocks. See ticket verbatim below. And to top it off, they are holding my customers hostage until a week from today when they run the corrective update. Hi Mike, While refining our processes to improve accuracy, some of our changes inadvertently over-corrected existing updates we had in place. We have noticed these and are correcting them currently. This unfortunately was one of the overridden updates. Thank you. Mike Lyon Aug 22, 2025, 11:00 AM EDT Do we know why it changed?
