<div class="">To some extent, yes.</div>

</div>
<div class="">In the JSON results download, the dst_addr key will provide the address that the probe sent its query to, however this will probably not be massively useful, as it’ll often be the address of a local router or other DNS cache.</div>

</div>
<div class="">Finding out what resolver a given client is using at the level of "is this Cloudflare/Google/Local ISP/etc" is a little harder and requires using either an NSID query, which you can set on Atlas measurements but may not be supported by all resolvers,
or a "whoami" style service like Akamai’s: <a href="https://developer.akamai.com/blog/2018/05/10/introducing-new-whoami-tool-dns-resolver-information" class="">https://developer.akamai.com/blog/2018/05/10/introducing-new-whoami-tool-dns-resolver-information</a>.</div>
