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".
