Hi! It depends on use case. For me, such probe would be fine for one-off measurements but for continuous measurements I would filter out such probe to avoid noise in data. However, when I looked on freifunk.net map I noticed that this network span across Germany, Switzerland, and Austria so even for one-off measurements usage of such probe is questionable because I never know where remote end of the tunnel is. If I understand correctly it can jump from country to country every day. In other words, such probe would be tricky to handle and user will have to be aware how such probe behave to properly handle data generated by it. Probably new system tag would be needed to mark such exotic probe.

All - I wonder whether this is a good idea or rather a really bad one... I have a free port on a Freifunk router where I could plug in a RIPE Atlas probe. Freifunk is a community where you - amongst other things - can offer a bit of your bandwidth to "the world". This connectivity sharing however is set up as a tunnel to various ISPs (for-profit companies and non-profit associations) as these would enjoy the "provider privilege": that in short is not to be held accountable for e.g. copy right infringements etc. ("Störerhaftung"). Anyhow: as part of this tunnel setup, the other end of the tunnel changes every 24 to 48 hours - and so does the upstream and therefore also the AS of the upstream provider. And now I am asking myself: a probe with ever changing upstreams/ASs - shall such an addition to the RIPE Atlas network be considered a fault or a feature? Any comments, anybody?

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.

Re: [atlas] RIPE Atlas Virtual Anchor Registration for DCS1 (sg-sin-as37989)
by Sanjeev Gupta 28 Jul '23

Hi, I am trying to install the virtual anchor of the ISO. Unfortunately, my experience with Unix went directly from Sun to Debian in the late 90s, so I am not sure of the intricacies of RHEL anaconda What (and in what format) do I answer here: 1. IPv4 address: 203.123.48.20 2. IPv4 Netmask: I tried 255.255.255.224, which it seemed not to like, so I tried /27, and then 27. 3. IPv4 gateway: 203.123.48.6 4. IPv6 address: 2405:fc00::20 (it keeps failing, should I enclose this in [] )? 5. IPv4 Netmask: I tried /64, and then 64 6. IPv4 gateway: 2405:fc00::6 Now it fails with: <snip>freedektop.NetworkManager.Settings.Connection.MissingPropert: ipv4.addresses: this propery cannot be empty for 'method=manual' And how do I backspace in the installer? Neither BKSP nor ^H seem to work.

Easy way to view DNS results?
by Micha Bailey 27 Jul '23

27 Jul '23

Hi, I’m wondering if I’m missing something - I ran a DNS measurement with 110 probes, and the results are in, but the site UI seems to only show the result status and time elapsed until response, but not the results themselves. Looking at the JSON from the result endpoint I’m seeing that it seems to return the raw binary response - is there a particular reason it can’t be parsed and displayed in a more human-readable format? I know there are libraries and tools that do result parsing, but being on mobile at the moment (and often) means those are somewhat less accessible as far as I’m aware.

Re: [atlas] DoH and DoT measurements
by Ponikierski, Grzegorz 26 Jul '23

Indeed “tls” flag seems to work. Thanks! After first try with DoT providers like one.one.one.one or dns.google I have additional question. When exactly FQDN from “target” is resolved to IP? Is RIPE Atlas resolve domain to IP only once during measurements creation or is each probe resolve domain to IP individually? It’s important details for me because I will work with FQDN that will resolve do different IP depending on user location so if it is resolved only once by RIPE Atlas system then probes will be using sub-optimal IPs to run tests.

Issues downloading large result files
by Ana 21 Jul '23

21 Jul '23

Hi everyone, I'm seeing something very strange when trying to download the result files for some large measurements. The download is a different size each time (sometimes 1.4GB, then 3.2GB, then back to 1 GB again) and checking the end of the file I can always see it's not complete as it stops in the middle of a measurement, closing brackets aren't there etc. I guess this is because of the size of the file, not sure if there's some sort of limit on RIPE Atlas? If anyone here has seen anything like this or has any advice on how to fully download the result that would be much appreciated! Thank you, Ana

Hello all, My name is Ioana Livadariu and I am a researcher at SimulaMet in Norway working on IP geolocation. I want to run a measurement campaign over RIPE Atlas which requires about 1M RIPE Atlas credits. If anybody can help me by sharing credits I would appreciate it a lot!

Credit request

Hi everyone, I would like to schedule some experiments to look at the prevalence and types of load-balancing in v4 and v6 networks. Running traceroutes with 32 paris repetitions on many probes unfortunately burns very quickly through credits. If you have some to spare and can donate to my account it would be much appreciated! Thank you, Ana
