destination_ip_responded field in traceroute measurements
Hi, to my delight I discovered that there is now a "destination_ip_responded" field contained in traceroute measurement results. I often want to know this and had to handle it myself until now so I'm very happy that this seems to be a built-in field now. I only wonder if this is a feature to stay (since it's not in the documentation yet), and if it is server side, i.e., always available independent of the probe firmware? Best, Malte

Hi Maite thank you for your message, and we are glad that you find the field `destination_ip_responded` useful. Yes it is here to stay and it is computed on the server side, by the Atlas controllers when they receive the probe reports. It's therefore independent from the firmware version, although it is present in the raw probe results only since its introduction on 16th October 2023. We have just updated the documentation https://atlas.ripe.net/docs/apis/result-format The field was already available for all results when using the RIPE Atlas measurement parsing library (Sagan) https://github.com/RIPE-NCC/ripe-atlas-sagan We have also amended the website user interface, showing a green tick in the Success column for the traceroute result when the destination is reached. Previously the traceroute was shown as successful if the last hop had responded, regardless of the fact that it matched the intended destination address or not, and this was leading to ambiguity in the interpretation of the results. Thank you and kind regards Francesco Iannuzzelli RIPE Atlas team

Thanks! However, it seems like the field was added to the documentation for firmware version 4570 only? I honestly don't know where it should be added since it's a server-side feature, but my first place to look for documentation is the newest version, so I think it should be at least added there :) Best, Malte

Thank you Maite for spotting this out, indeed it needs to be added to all versions >4570, I have updated the documentation now https://atlas.ripe.net/docs/apis/result-format/ kind regards Francesco
