The .com server tells the querier the names of the xxxxx.com nameservers,
and the querier then asks one of those servers to look up www.xxxxx.com.
It returns
www.xxxxx.com. CNAME www.yyyyy.com.
If this nameserver has www.yyyyy.com in its cache, it will also include
www.yyyyy.com. A <address of your web server>
in the response, so the query will be finished. If not, the original
nameserver then starts the whole process over, looking up www.yyyyy.com.
