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