Delegation
step query auth servers 1 google.cn. . (a,h,f,g,e,i,d,j,l,b,k,m,c).root-servers.net. 2 google.cn. cn. a.dns.cn. c.dns.cn. d.dns.cn. ns.cernet.net. b.dns.cn. e.dns.cn. 3 google.cn. google.cn. (ns1,ns4,ns3,ns2).google.com.
We pick a.root-servers.net , one of the 13 root servers (1), and ask it about google.cn and learn that cn is delegated to six name servers (2), so we ask a.dns.cn where we learn that google.cn is delegated to four name servers, including ns1.google.com (3), so we ask that one and get the following answer:
