We pick h.root-servers.net , one of the 13 root servers (1), and ask it about i3.sina.com.cn and learn that cn is delegated to six name servers (2), so we ask e.dns.cn where we learn that sina.com.cn is delegated to four name servers, including ns2.sina.com.cn (3), so we ask that one where we see a CNAME from i3.sina.com.cn to capella.sina.com.cn , so we have to start all over again. We already know that ns2.sina.com.cn is authoritative for sina.com.cn (4) and ask it about capella.sina.com.cn and get the following answer:
