The DNS-specific option use_probe_resolver is mentioned in <https://atlas.ripe.net/docs/measurement-creation-api/> but with little indication of the semantics.

My experience is that some probes (with the default retry=0) return several responses, with the same "prb_id", but different "from". I assume it means the probe had several resolvers configured and tried them all.

The semantics of 'use_probe_resolver' is that the probe will send a DNS query to all resolvers listed in /etc/resolv.conf that match the particular IP version of the measurement. I assume that if you want just one result, you can extract that during processing the results. Philip
