dig +trace equivalency
Hi, I use to use +trace option in dig command. Is there any same function equivalency in Atlas's DNS measurement tool? Thank you in advance. -- -dikshie-

dig +trace is not very reliable, and does not work with all resolvers. And, no, I don't think there is an equivalent for the Atlas probes. It would require some resolver-like logic in the probe.

It is in principle possible to simulate resolver-like logic without updating the probe. In fact, I worked on a team to do just that at a RIPE Atlas Hackathon a couple years ago. You can see the results on GitHub here: https://github.com/shane-kerr/ripe-atlas-shrugd This was just a hack, but the technique should be usable to do something similar to "dig +trace".

Thank you for the pointer to your hackathon project. I will take a look later this weekend. Best Regards, Dikshie

I see. Previously, I thought using nsid is enough but I found nsid information from my target dns servers are not reliable. There is no way for me to identify the servers. (looks like the dns server operator must fix the nsid text). Best Regards, -- -dikshie-
