In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can. Inferred improvements during Nov 2023: ASN Name Fixed-By 14031 SCXY 2023-11-11 Further information for the inferred remediation is available at: https://spoofer.caida.org/remedy.php Source Address Validation issues inferred during Nov 2023: ASN Name First-Spoofed Last-Spoofed 209 CENTURYLINK-US-LEGACY-QWEST 2016-08-16 2023-11-30 20412 CLARITY-TELECOM 2016-09-30 2023-11-30 25787 ROWE-NETWORKS 2016-10-21 2023-11-26 271 BCNET 2016-10-24 2023-11-26 3549 LVLT-3549 2016-11-16 2023-11-17 14031 SCXY 2018-10-18 2023-11-14 22883 CONDENAST 2019-05-29 2023-11-28 55016 IMPER-AS-1 2021-05-18 2023-11-18 46997 2021-12-22 2023-11-30 394414 E2WS 2022-05-08 2023-11-09 12183 TALKIE-COMMUNICATIONS 2022-12-10 2023-11-28 3701 NERONET 2023-04-18 2023-11-30 400282 2023-04-27 2023-11-25 46690 SNET-FCC 2023-05-20 2023-11-25 20119 ARROW 2023-10-19 2023-11-27 396356 MAXIHOST 2023-11-11 2023-11-11 Further information for these tests where we received spoofed packets is available at: https://spoofer.caida.org/recent_tests.php?country_include=usa,can&no_block… Please send any feedback or suggestions to spoofer-info(a)caida.org

"Lit" Buildings
by Mike Hammett 07 Dec '23

07 Dec '23

For those of you who list your network (usually wireline, but sometimes wireless) with third parties, are you supplying just the KMZ or lit buildings as well? If lit buildings, are you including residential? How are you defining near-net? ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

The rise and fall of the 90's telecom bubble
by Dave Taht 06 Dec '23

06 Dec '23

Aside from me pinning the start of the bubble closer to 1992 when commercial activity was allowed, and M&A for ISPs at insane valuations per subscriber by 1995 (I had co-founded an ISP in 93, but try as I might I cannot remember if it peaked at 50 or 60x1 by 1996 (?) and crashed by 97 (?)), this was a whacking good read, seems accurate, and moves to comparing it across that to the present day AI bubble. https://www.fabricatedknowledge.com/p/lessons-from-history-the-rise-and In the end we sold (my ISP, founded 93) icanect for 3 cents on the dollar in 99, and I lost my shirt (not for the first time) on it, only to move into embedded Linux (Montavista) after the enormous pop redhat's IPO had had in 99. The company I was part of slightly prior (Mediaplex) went public December 12, 1999 and cracked 100/share, only to crash by march, 2000 to half the IPO price (around $7 as I recall), wiping out everyone that had not vested yet. I lost my shirt again on that and Montavista too and decided I would avoid VCs henceforth. I am always interested in anecdotal reports of personal events in this increasingly murky past, and in trying to fact check the above link. So much fiber got laid by 2000 that it is often claimed that it was at least a decade before it was used up, (the article says only 2.7% was in use by 2002) and I have always wondered how much dark, broken, inaccessible fiber remains that nobody knows where it even is anymore due to many lost databases. I hear horror stories... The article also focuses solely on the us sector, and I am wondering what it looked like worldwide. I believed in the 90s we were seeing major productivity gains. The present expansion of the internet in my mind should not be much associated with "productivity gains", as, imho, reducing the general population to two thumbs and a 4 inch screen strikes me as an enormous step backwards.

Any comprehensive listing of where Google's IPs originate from?
by Drew Weaver 06 Dec '23

06 Dec '23

Hello, We are trying to reduce latency to a region in Google Cloud which we are in the same city of. Latency is currently about 22ms rt for the traffic to go 9 miles. I am having the hardest time finding any comprehensive list of what exchanges, transit, etc their IP addresses are being announced over. Specifically trying to get closer to addresses in these prefixes: 34.162.192.0/18 34.162.64.0/18 Any info is greatly appreciated. Thanks, -Drew

Fiber/OSP Technician Training and Apprenticeship Programs
by Rhys Barrie 05 Dec '23

05 Dec '23

Hey all, I've recently been working with our county's broadband task force, investigating the expansion and equity of broadband networks on a local and state level. Through that, it's become clear that there's a painful shortage of fiber / outside plant technicians in the state of Michigan (if not nation-wide) in order to fulfill the workforce requirements of maintaining the current broadband fiber infrastructure in the state, much less to fuel fiber expansion, and especially in rural areas. There appear to be few options for training the required workforce, especially outside of the large enterprises that have the resources to run their own internal programs, and small (or even mid-sized) ISPs seem to be left with predominantly informal person-to-person transfer of internal knowledge, assuming that they have the required internal knowledge in the first place. This need for a qualified workforce is exacerbated in the face of the multitude of state and federal programs to encourage broadband internet expansion and equity, such as the upcoming $42.5 billion in BEAD grant funding and corresponding construction starting in ~12-18 months state- and nation-wide. As a result, our workforce development team over here at Mott Community College (Genesee County, MI) is working to develop a fiber / outside plant training and apprenticeship program in order to help address this shortage of qualified personnel and training options at a local and state level. We're looking for some industry contacts that would be interested in collaborating with us to establish high-level requirements regarding what skills need to be taught to prospective fiber / outside plant technicians, what qualifications trainees should have after completion in order to fulfill current workforce demands, and to otherwise provide input in sketching out a high-level curriculum. We're looking for feedback from a wide cross-section of industry stakeholders -- large enterprise backbone transit providers, rural residential ISPs, fiber co-ops and municipal networks, operations and outside plant managers, etc. -- in order to determine what the industry wants and needs, and how the entire community college system can help meet those needs. If anyone thinks that they have valuable input to provide regarding these workforce requirements, or knows the right people to talk to, please reach out and let me know!

What are these Google IPs hammering on my DNS server?
by John Levine 05 Dec '23

05 Dec '23

At contacts.abuse.net, I have a little stunt DNS server that provides domain contact info, e.g.: $ host -t txt comcast.net.contacts.abuse.net comcast.net.contacts.abuse.net descriptive text "abuse(a)comcast.net" $ host -t hinfo comcast.net.contacts.abuse.net comcast.net.contacts.abuse.net host information "lookup" "comcast.net" Every once in a while someone decides to look up every domain in the world and DoS'es it until I update my packet filters. This week it's been this set of IPs that belong to Google. I don't think they're 8.8.8.8. Any idea what they are? Random Google Cloud customers? A secret DNS mapping project? 172.253.1.133 172.253.206.36 172.253.1.130 172.253.206.37 172.253.13.196 172.253.255.36 172.253.13.197 172.253.1.131 172.253.255.35 172.253.255.37 172.253.1.132 172.253.13.193 172.253.1.129 172.253.255.33 172.253.206.35 172.253.255.34 172.253.206.33 172.253.206.34 172.253.13.194 172.253.13.195 172.71.125.63 172.71.117.60 172.71.133.51 R's, John

sigs wanted for a response to the fcc's NOI for faster broadband speeds
by Dave Taht 02 Dec '23

02 Dec '23

Over here: https://docs.google.com/document/d/19ADByjakzQXCj9Re_pUvrb5Qe5OK-QmhlYRLMBY… Us bufferbloat folk have been putting together a response to the FCC's NOI (notice of inquiry) asking for feedback as to increasing the broadband speeds beyond 100/20 Mbit. "Calls for further bandwidth increases are analogous to calling for cars to have top speeds of 100, 200, or 500 miles per hour. Without calling also for better airbags, bumpers, brakes, or steering wheels, (or roads designed to minimize travel delay), these initiatives will fail (and are failing) to meet the needs of present and future users of the internet." Comments (and cites) welcomed also! The text is still somewhat in flux... -- :( My old R&D campus is up for sale: https://tinyurl.com/yurtlab Dave Täht CSO, LibreQos
