Delegation
step query auth servers 1 i.u-tokyo.ac.jp. . (e,i,m,d,g,f,j,a,k,l,c,h,b).root-servers.net. 2 i.u-tokyo.ac.jp. jp. (b,f,d,g,c,a,e).dns.jp. 3 i.u-tokyo.ac.jp. u-tokyo.ac.jp. (dns2,dns3,dns1).nc.u-tokyo.ac.jp.
We pick e.root-servers.net , one of the 13 root servers (1), and ask it about i.u-tokyo.ac.jp and learn that jp is delegated to seven name servers (2), so we ask b.dns.jp where we learn that u-tokyo.ac.jp is delegated to three name servers, including dns2.nc.u-tokyo.ac.jp (3), so we ask that one and get the following answer:
