RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all)
by Lukas Tribus 19 Mar '23

19 Mar '23

Hello, so 100.64/10 is used in CGNAT deployments requiring service providers (that is AS operators) to drop 100.64/10 on the border to other AS in BGP and in the dataplane, as per RFC6598 section #6 Security Considerations [1]. Within an AS though traffic from 100.64/10 can very well bypass CGNAT for AS local traffic to reduce state/logging. This appears to be quite common and it makes a lot of sense to me. At the same time folks like team-cymru are picking up this prefix for their bogon lists with the following description [2]: > A packet routed over the public Internet (not including > over VPNs or other tunnels) should never have an address > in a bogon range. It would be quite a bad idea to drop 100.64/10 on a firewall or servers, when legitimate traffic can very well hit your infrastructure with those source IPs. Thoughts?

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

Good people, Last year, I collected some data for my study from this list. I published a summary of the data for a short time and recently sent a snapshot regarding metro area access technologies. I am currently writing my paper and would love to have some additional data points. If anyone who has ***not yet contributed*** would like to do so, I am still collecting data here: https://forms.gle/ypcCZvrHbKXRbXqn9 Sincerely, Etienne -- Ing.
