Re: [atlas] Problems with DNS measurements and NSID

The 'normal' mode for DNS queries is that they get sent to one server. So you would get one reply each time the measurement is performed.

The exception is when the measurement is to query the probe's local DNS resolvers. In that case, up to three resolvers are queried and you can get as many replies.

In the past, each replies would be an independent Atlas result. However, our storage back-end cannot really handle that. So the code was changed that all three replies are grouped into a single Atlas result.

Hence, in general, an Atlas DNS result can contain multiple DNS replies. But only if you select the 'use the probe's local resolvers' option. Thanks for the clarification Philip. good to know.
