What do you think about the "cloudification" of mobile?
by Michael Thomas 28 Jan '22

28 Jan '22

There was an article in the Economist (sorry if it's paywalled) about Dish entering the mobile market using an AWS backend. I don't think that AWS brings much more than compute for the most part so I don't really get why this would be a huge win. A win maybe, but a huge win? I can certainly see that not having tons of legacy and accreted inertia is big win, but that's true of any disruptor. In the end they still need base stations, spectrum, backhaul and all of that to run their network, right? Am I missing something, or is this mainly hype?

In 2022 there are many encryption options for DNS. There are also things like DNSSEC and DANE for ensuring authenticity over cleartext. In addition, if the latest US Federal guidance is anything to go by, we may be witnessing the first big nail being put into the cleartext DNS coffin.

Wondering what others in the small to medium sized networks out there are using these days for netflow data collection, and your opinion on the tool? Thanks!

VIDEO | "Internet Innovators" w/ Steve Crocker + N84 Agenda + more
by Nanog News 27 Jan '22

27 Jan '22

New Episode of Internet Innovators!*Crocker Reveals a Behind-the-Scenes Look at Internet History* Steve Crocker is known as the man who wrote the instructions for the Internet - in his twenties. But at one time, he was just a young graduate student trying to solve a set of problems. "We knew we didn't know all the answers - we were not going to design a complete system, we were going to design a toolkit," Crocker said of the "informal group" which included life-long friend Vint Cerf and other now-famous Internet pioneers. In fact, Crocker said when he was given the "clerical task" of writing down what they were doing, he had many a sleepless night. "I was fearful the mere act of writing down what we were thinking about might trigger a backlash," he continued. "No one had chartered us, we had no authority. I was afraid it might seem like we were being presumptuous - like we were insisting that we were in charge. It caused a number of sleepless nights," he said. *Watch the full interview NOW on NANOG TV.* *WATCH NOW <https://www.nanog.org/news-stories/nanog-tv/internet-innovators/steve-crock…>* *NANOG 84 Agenda is Live * *Save the date! * Coordinate your calendars now, so you are sure not to miss out on any of the incredible upcoming talks and social hours offered virtually + in-person!

Long hops on international paths
by PAUL R BARFORD 25 Jan '22

25 Jan '22

Hello, I am a researcher at the University of Wisconsin. My colleagues at Northwestern University and I are studying international Internet connectivity and would appreciate your perspective on a recent finding. We're using traceroute data from CAIDA's Ark project for our work. We've observed that many international links (i.e., a single hop on an end-to-end path that connects two countries where end points on the hop are identified via rDNS) tend to originate/terminate at the same routers. Said another way, we are observing a relatively small set of routers in different countries tend to have a majority of the international connections - this is especially the case for hops that terminate in the US. For example, there is a router operated by Telia (AS1299) in Chicago that has a high concentration of such links. We were a bit surprised by this finding since even though it makes sense that the set of providers is relatively small (i.e., those that offer global connectivity), we assumed that the set of routers that used for international connectivity within any one country would tend to be more widely distributed (at least with respect to how they appear in traceroute data - MPLS notwithstanding). We're interested in whether or not this is indeed standard practice and if so, the cost/benefit for configuring international connectivity in this way? Any thoughts or insights you might have would be greatly appreciated - off-list responses are welcome. Thank you. Regards, PB Paul Barford University of Wisconsin - Madison

Operator survey: Incrementally deployable secure Internet routing
by Yixin Sun 25 Jan '22

25 Jan '22

Dear Nanog, We appreciate that your time is very precious, but we wanted to ask you for your help in answering a brief survey about a new secure routing system we have developed in a research collaboration between ETH, Princeton University, and University of Virginia. We'd like to thank those of you who have already helped us fill out the survey and provided insightful feedback. Your input is critical for helping inform our further work on this project. Here is the link to our survey, which takes about 10 minutes to complete, including watching a brief 3-minute introductory video: https://docs.google.com/forms/d/e/1FAIpQLSc4VCkqd7i88y0CbJ31B7tVXyxBlhEy_zs… Our architecture, called Secure Backbone AS (SBAS), allows clients to benefit from emerging secure routing deployments like SCION by tunneling into a secure infrastructure. SBAS provides substantial routing security improvements when retrofitted to the current Internet. It also provides benefits even to non-participating networks and endpoints when communicating with an SBAS-protected entity. We currently have a functional prototype of this network using SCIONLab (for the secure backbone) and the PEERING testbed (to make outbound BGP announcements). Our ultimate aim is to develop and deploy SBAS beyond an experimental scope, and the input of network operators that would actually have to run these PoPs would greatly benefit this project and help make secure routing a reality. With kind regards, Prateek, Adrian, and Yixin

Telia is now Arelion
by Justin Krejci 25 Jan '22

25 Jan '22

https://www.arelion.com/ <sigh> Since all other work is now complete in the world I should have plenty of time to update documentation, billing, labels, port names, route-maps, contact email addresses, etc. After watching their marketing video I learned the pronunciation of Arelion is not R-Lion but is actually A-Ray-Lee-On but I may continue thinking of it as R-Lion because it is shorter and it just sounds cooler in my head.

It’s the frequency and the knowledge to configure the software and equipment that is still prohibitively expensive in many cases. And frankly, if you are only providing fixed access to 500 users, I’m not sure even the AWS solution is necessary. Because if you can configure the transport and the software you can probably run a handful of KVM servers.

I am looking for someone in network engineering/design at Midcontinent Communications (AS11232) who can explain why the IPv6 PD is set to 64 bits. I believe that this is a poor design decision and would like to understand how this decision was made. Thanks. - Brian

I'd like to point y'all at NTIA's RFC for the many billion of upcoming USA broadband funds, here: https://ntia.gov/files/ntia/publications/fr-iija-broadband-rfc.pdf which has some really good questions on it (out of the 36), q12-16 in particular. Comments are due feb 4th, if anyone would like to contribute some.
