ra : recursion available
    The nameserver is ready to ask other nameservers for the record we
    queried.

As the 'aa' flag is also missing above, the answer is not authoritative.

> >;; flags: qr aa; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 0

aa : authoritative answer
    The nameserver is authoritative for the zone of the record that we
    queried.

As the 'ra' flag is also missing above, the nameserver will not do a
lookup for you for records it does not know about.
