Chuck,
I am talking from the point of view of a DNS server not a client resolver.
Anyways note that the entire CNAME chain is from the same wordpress zone, so
the chain should be followed without requiring an additional query and there is
no need for trying to short circuit the process by addin
Mark,
Is the first parsing step over both Answer and Additional sections, I was under
the impression that "Named" parses the response into RRSets from the Answer
section and if there is a CNAME chain both within the same zone it follows the
chain as well. But no additional sections are checked

would receive if you were a DNS server performing an authoritative query t

The RFC rules on CNAMEs is fairly tight but I am seeing an increasing
amount of traffic with misconfigured CNAMEs some of which are accepted
by BIND as valid responses. The examples capture three trends, note
these are actual responses:
