Handling subdomain ?

[Mark.Andrews at nominum.com]

	Section 4.3.2, Step 3(a) applies first.

	"a. If the whole of QNAME is matched, we have found the
	    node.

	    If the data at the node is a CNAME, and QTYPE doesn't
	    match CNAME, copy the CNAME RR into the answer section
	    of the response, change QNAME to the canonical name in
	    the CNAME RR, and go back to step 1.
	
	    Otherwise, copy all RRs which match QTYPE into the
	    answer section and go to step 6."
	   
	Note:
	1. this is independent of type.
	2. "all RRs which match type" may be zero.
