Can be useful to estimate proximity between probe and DNS and to detect nasty middle boxes. To limit overhead on Atlas side, IP header can be provided as raw data to decode on end-user side.

In my scenario I'd like to see TTL/Hop Limit of packets received in DNS measurements. So I'm curious if anyone else think it would be a useful feature and if there is some demand for such a feature - maybe the Atlas team could consider implementing it?
