Requesting Credits for Research
by Alex Gamero-Garrido 29 Jul '23

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.

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?

My probe's not doin' IPv6
by Edward Lewis 23 Apr '22

23 Apr '22

General question… My probe was doing IPv6 until 15 July 2021 but not it is not. Is there any way to discover why it is no longer IPv6’ing? I did change my ISP connection equipment about that time, so something did change on my end. But IPv6 works for other devices. When I go to www.ripe.net <http://www.ripe.net/> it tells me I came from an IPv6 address. The device has been pretty steady - 99.71% the last week, 99.91% for the last month (30days). It was off-line 29 minutes earlier today (the notice made me think to look), but never off line more than 10 minutes since mid-July. There’s one stretch of 34d+ of continuous uptime. Run-of-the-mill home connection via a cableTV company. Is there anyway to ask a probe why it doesn’t have an IPv6 address (via DHCP)? Ed

Location of probe controllers
by Malte Appel 01 Feb '22

01 Feb '22

Hi, I was looking at the built-in traceroute measurements and noticed additional targets (ctr-*.atlas.ripe.net) apart from the DNS root servers. As I understand it, these are the controllers for the probes. However, I was wondering where they are physically located and could not find any clear information about that. My guesses from the DNS names are based on IATA airport codes: ctr-ams02.atlas.ripe.net (Amsterdam, NL) ctr-ams03.atlas.ripe.net (Amsterdam, NL) ctr-ewr01.atlas.ripe.net (Newark, NJ, US) ctr-fnc01.atlas.ripe.net (Funchal, PT) ctr-nue13.atlas.ripe.net (Nürnberg, DE) ctr-nue17.atlas.ripe.net (Nürnberg, DE) ctr-sin02.atlas.ripe.net (Singapore, SG) Can anyone confirm or correct these locations? Best, Malte

Is there a procedure to move a software probe to a new device
by Peter Garner (iPad) 01 Feb '22

01 Feb '22

Noob question. I set up my software probe on a Debian 10 box which has quite a few small servers on it. However, I intend to move it onto a Raspberry Pi, so I was wondering if there's a specific procedure to follow to preserve existing settings? Only the internal IP address will change; the external remains the same.

Can't access the serial in SOA records from the API
by Nathan Larsen 26 Jan '22

26 Jan '22

Hi, Does anyone know a way to access the serials from SOA records with the Ripe Atlas API? I have been running a variety of DNS measurements with the query type being SOA, but have not been able to determine how to get serial numbers over the course of the measurement. Any guidance would be appreciated, Nate Larsen

Dears, Any reason why my daily income in credits is zero even though my probe is almost online everyday ? My probe ID : 32256 Also I would appreciate few donations ( 4 million credits) on credits as I need to initiate new measurements ?

probe V2 status lights
by Jaap Akkerhuis 18 Jan '22

18 Jan '22

There used to be information telleing what the lights mean. It seems to be gone. After a lot of searching around one finds some information about blinking orage lights but all leds in version 2 are green colored so I guess this cvers V3 (or V1?) probes. have probes V2 been abandoned by Ripe-Ncc? jaap

Re: [atlas] Possible paging bug on RIPE Atlas Probes page with iltered results
by T 14 Jan '22

14 Jan '22

Hello, It's not you, it's not your browser. It is indeed a bug that exists since the new design of the RIPE Atlas website (Quite a few months ago), I reported it in the survey of usability and improvement of the site, but apparently it still exists to this day. You can use these urls as a workaround: Pages: public=1, public=2, public=3, etc. Status=0: Never Connected Status=1: Connected Status=2: Disconnected country=US: Country code https://atlas.ripe.net/frames/probes/?public=1&search=&status=0&af=&country… https://atlas.ripe.net/frames/probes/?public=1&search=&status=1&af=&country… https://atlas.ripe.net/frames/probes/?public=1&search=&status=2&af=&country… At least it's a little more usable this way. Apparently the menus of the old design are still standing in the new design, so it does not recognize the filters.

Incorrect location of a probe
by Hugo Salgado 11 Jan '22

11 Jan '22

Hi RIPE Atlas. Have a happy new year! I'd like to know how you can report a probe that has a bad geolocation. It's #29811 that appears in southern Chile, but its AS and traceroutes appear to be in Canada. Unfortunately it affects all measurements that try to group geographically by country :( If the host does not cooperate, could a system tag be added indicating "suspicious location"? Thanks a lot! Hugo
