The way I understand it, there is a resolver, but the clients can also
get domain name data without going through a resolver. For instance,
the HTTP server you are currently talking with could push domain name
data to you (may be with a variant of DoH) and you may accept it, and
even populate your cache with it (the rationale being that the HTTP
server for example.com may be at least as authoritative for
foobar.example.com than the resolver).
