Delegation

14.in-addr.arpa..(h,c,a,m,d,f,e,b,j,g,l,i,k).root-servers.net.
24.in-addr.arpa.in-addr.arpa.(b,f,a,c,e,d).in-addr-servers.arpa.
34.in-addr.arpa.4.in-addr.arpa.(ns1,ns2).level3.net.
We pick h.root-servers.net, one of the 13 root servers (1), and ask it about 4.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask b.in-addr-servers.arpa where we learn that 4.in-addr.arpa is delegated to two name servers, including ns1.level3.net (3), so we ask that one and get the following answer:
