Is malicious asymmetrical routing still a thing?
by John Levine 13 Mar '23

13 Mar '23

Back in the olden days, a spammer would set up a server with a fast broadband connection and a dialup connection, and send out lots of spam over the broadband connection using the dialup's IP address. Since mail traffic is quite asymmetric, this got them most of the broadband speed, and when the dialup provider cancelled their service, they could just dial into someone else. Or maybe work through that giant pile of AOL CD-ROMs we all had. The broadband provider often wouldn't notice since it wasn't their IP and they didn't get the complaints. Is this still a thing? Broadband providers fixed this by some combination of filtering port 25 traffic both ways, and BCP38 so you can only send packets with your own address. Do providers do both of these? More of one than the other? TIA. R's, John

ITNOG7 may 19th
by Brian Turnbow 10 Mar '23

10 Mar '23

Hello everyone, Itnog7 is taking place in Bologna May 9th and 10th and we have published our CFP. Topics Past event feedback has shown interest from the attendees in sessions that are practical and applicable to their networks. This year we will be giving preference to presentations and tutorials that benefit the Italian operators community on the following topics * Ever changing network technologies drive the question of how to define a "network engineer". What is the evolution? * Share your experiences, choices, best practices, and business decisions on ipv6 deployment and ipv4 exhaustion * SDN, Telemetry and Artificial intelligence are redefining Network monitoring and orchestration, what are you doing? * Strategic Italian infrastructure from new undersea cables, new datacenters to ixps, Investments are being made tell us about them and who decides what is "strategic"? * Access and backbone networks: design , technologies and operations * Peering and Interconnections: tools, strategies and useful information for building and maintaining a resilient Italian Internet Have another topic? If it is technical and can be of interest to the community send it in. Submissions will only be accepted if they match the requirements defined herein. The topic of the presentation should be technical, with strong focus on the development, engineering and operation of internet networks. The ITNOG community is quite sensitive to keeping presentations non-commercial, and product marketing talks will not be accepted. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. Repeated audience feedback shows that the most successful talks are lightning talks that focus on operational experience, research results, or case studies. To submit a presentation to the Program Committee make sure to include: * An abstract of your presentation ( in English or Italian ) * The requested time frame * A draft or the final version of the slide deck to be presented. * Presentations may be in English or Italian, and will be divided between lightning talks (max7 minutes) and tutorials or presentation between 10 and 30 minutes in length. A 5 minute Q&A session will follow each presentation. Submissions should be sent to itnog-pc(a)lists.itnog.it no later than 15th of April 2023. Event information is available here https://www.itnog.it/itnog7/ Even if you do not want to present, you are welcome to come and experience an Italian style Nog. Bologna you know is the home of lasagna. Brian

A blatant podcast plug
by Dave Taht 10 Mar '23

10 Mar '23

I rather enjoyed doing this podcast a few weeks ago, (and enjoy this podcast a lot, generally), and it talks to what I've been up to for the past year or so on fixing bufferbloat for ISPs. https://packetpushers.net/podcast/heavy-networking-666-improving-quality-of… I am kind of curious as to how much XDP and EBPF now exist in the nanog universe and other applications y'all are finding for it? -- Come Heckle Mar 6-9 at: https://www.understandinglatency.com/ Dave Täht CEO, TekLibre, LLC

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.

NY Verizon FIOS IPv6 routing issue
by Robert Blayzor 08 Mar '23

08 Mar '23

Any Verizon IP engineers lurking on this list that can contact me about a recurring and chronic IPv6 routing issue in the upstate NY Verizon FIOS network. Getting feedback from several customers that have valid IPv6 PD from FIOS but routing is broken 2-3 hops out in Verizons network. This is causing major service issues with anyone that has IPv6 enabled. Happy to provide details or work the proper channels; if only you could easily find that information... -- inoc.net!rblayzor Email: rblayzor.AT.inoc.net PGP: https://pgp.inoc.net/rblayzor/

Re: Re[2]: RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all)
by Lukas Tribus 08 Mar '23

08 Mar '23

Hello, > It is just that, marketing. I disagree, authoritative and accurate product description and documentation of the tools used by the public matter a lot. If a ticket lands on my desk because a third party misuses a tool, I want to point to a single authoritative source of information. > It doesn't mean you have to follow it to the letter. I know that, you know that. That doesn't solve my problem. What solves my problem is accurate documentation and education. > Why not take this up with them Team Cymru directly? This is an operational networking issue that goes beyond the bogon list of Team Cymru. I am now in contact with Team Cymru, to improve the situation there, but that is just an example. My intention is to explain the problem and educate. Thanks, Lukas
