To be correct; it's an operational issue. SLAAC works as designed with IPv6 
renumbering.


slaac - being stateless 'n all - was not designed with flash renumbering 
in mind because flash renumbering needs some degree of state 
synchronisation on all devices on the path between the provisioning 
system issuing the prefix and the end device. So in this sense it is a 
protocol issue, albeit an issue that was outside the design scope of the 
protocol.



Imagine if the mobile operator swapped your mobile phone number midstream.


mobile phone numbers are stateful. You don't need to change phone number 
every time you're handed off to a different cell.

Is this a flaw, or is it by design?


this is a known protocol issue with slaac.  There's some discussion 
about it in rfc8978 and draft-ietf-6man-slaac-renum.

Re: [atlas] dead v1 probe

have there been software updates for v1 probes recently?  I've heard
about a few v1 probes that have died "just last week" - mine among
them (#461), fell off the net with "Firewall Problems Suspected",
but it's no longer even ARPing properly (= either it totally lost
its config and wants DHCP now, which there isn't in this network,
or it just died)...

So knowing whether this is a more widespread issue and possible reasons
would help me to decide how much effort to invest in debugging this.


as you mention it, one of my v1 probes died on sunday:


Your probe 127 has been disconnected from the RIPE Atlas infrastructure since 
2020-05-31 21:55:58 UTC.


Did this coincide with a software update or something on the control side?

ooh, CAIDA.  My favourite!  Just sent 100m.

Re: [atlas] Probes were incorrectly not tagged with the stability tags

Just for clarity, we do not yet tag probes as being stable over IPv5.


best to be prepared all the same.

Dear RIPE Atlas users,

I am a PhD-student and would need RIPE Atlas credits in order to perform 
large-scale traceroute experiments.


If you have credits to share, I would appreciate it.

Hi Nils,

Folks,

I teach computer science at Case Western Reserve University.  I have a 
group of students working on a research project to characterize 
certain aspects of DNS and HTTP interactions on the Web.  To get a 
representative measurement, we need to resolve hostnames from top-1M 
websites from a large number of widely dispersed probes.  So we need a 
large amount of credits and I was wondering if I could ask folks for 
help.  My back of the envelop calculations suggest we are short of 
~200M credits.   I realize it’s a large amount, but we would take any 
help we can get and will conduct as credible measurement as we can 
with the credits we assemble!  Please note that my RIPE Atlas account 
is associated with mail alias mi...@case.edu 
 (not the default email address I am sending 
from), so please use “mi...@case.edu ” for 
credit transfer if you can help.


Many thanks in advance!

Greetings! I'm a PhD student at Tsinghua University, China.
Recently a large-scale measurement via RIPE Atlas is needed for my
research. However, as a new user I don't have any credit to proceed,
and unfortunately the time doesn't allow me 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, a million)?
My account at RIPE NCC is lc...@mails.tsinghua.edu.cn


sure - just sent you 10m.
