29 Jul '23

Hi folks, My name is Alexander Gamero-Garrido and I'm a 5th year PhD student at CAIDA, UC San Diego. We're soon launching a large traceroute campaign for research and could use your generous donation of credits. We'll need about 150 million credits, but any partial amount that gets us closer to that goal is welcome and greatly appreciated. My account is agamerog at eng.ucsd.edu Thank you, Alex -- *Alex Gamero-Garrido* *PhD Student, Computer Science* Web: cseweb.ucsd.edu/~agamerog Center for Applied Internet Data Analysis (CAIDA) San Diego Supercomputer Center UC San Diego Pronouns: He/Him/His <https://inboxwhenready.org/?utm_campaign=signature&utm_medium=email&utm_sou…> I'm using Inbox When Ready <https://inboxwhenready.org/?utm_campaign=signature&utm_medium=email&utm_sou…> to protect my focus.

upgrading an original soft probe
by Randy Bush 08 Jun '23

i have a probe, 1000004, on a deb 10 vm that was installed in the rotterdam hackathon. the detritus looks as if it was built using a deb install of atlasswprobe-5000-1.deb. two days ago, it stopped working in some way; i have not pursued, figuring i was dealing with an antique. is there a path to make it current? randy

Probe DHCPv6 support
by Aleksi Pirttimaa 19 May '23

19 May '23

Hi! I recently received my v4 probe and I'm very happy with it. But unfortunately it doesn't support DHCPv6. I present a practical reason for implementing a DHCPv6 client on the probe. You see, my ISP doesn't send router advertisements with the prefix for stateless autoconfiguration set, and instead DHCPv6 must be used. I believe their decision could have something to do with the fact that the regulating body here requires ISP's to prevent IP address spoofing in consumer plans. And to meet that requirement my ISP may be using a feature similar to Cisco's IP source guard, where switch ports and/or mac addresses are passively associated to leased ip's or prefixes, breaking SLAAC. Unfortunately they hate letting consumers talk with their engineers so it's difficult to speculate this further. For now, I've put a stateful firewall appliance in front of the probe which provides SLAAC, it works just fine. Do you think a DHCPv6 client should be implemented?

Request RIPE Atlas Credit for Research
by 卫蕴泽 28 Apr '23

28 Apr '23

Dear all, Greetings! I'm a senior student at Tsinghua University, China. Recently I'm working on my graduation project, which is a IP infrastructure mapping research that requires large-scale network measurement via RIPE Atlas to verify my method. However, a simple traceroute with 6 probes need 10K+ credits. As a new user I don't have any credit to proceed, and I've no time to earn them by myself. So I'm here to ask for help. Is it possible for anyone generous enough to offer me some RIPE Atlas credits (like, 10M)? My account at RIPE NCC is fenglan.chn(a)gmail.com, my education email is weiyz19(a)mails.tsinghua.edu.cn and my student ID is 2019011285. Many thanks for your help! Sincerely, Yunze Wei

a link for comparing DNS resolvers
by Michael Rabinovich 04 Apr '23

04 Apr '23

Folks, FYI, Nick Kernan, my Masters student, has deployed a web portal that facilitates the comparison between various DNS resolvers, including ISP-provided and some influential publicly available resolvers (Google’s public DNS, OpenDNS, Quad9, and Cloudflare). The comparison is based on two factors: the latency of DNS resolutions and the latency of TCP handshake with the CDN edge server selected through a given resolver. The results are based on recurrent monthly measurements from RIPE Atlas probes that have both IPv4 and v6 connectivity, have an ISP-provided resolver available for comparison, and which meet certain requirements regarding probe versions and reliability. You can specify the desired month of measurement, a region of interest, and the CDNs to analyze. You can access Nick’s portal through https://dns-web-portal.netlify.app/ <https://dns-web-portal.netlify.app/> The details of the methodology are in Nick’s thesis, which awaits some copyright permissions before being made publicly available. In the meantime, Nick (cc’ed) and I would be happy to answer any questions. Regards, —Misha Rabinovich
