When the CNAME refers to a name that is out of zone and the target zone is below
a zone that the server serves you will have CNAME (DNAME) + referral.
4.3.2 loops.
pass 1 -> 3a (adds CNAME, AA is set as it matches the question
section, QNAME is updated).
pass 2 -> 3b (we have a partial match with a bottom of zone cut which
adds the referral).
