12.104.172.in-addr.arpa..(b,h,f,l,c,k,d,a,j,e,i,g,m).root-servers.net.
22.104.172.in-addr.arpa.in-addr.arpa.(a,c,e,b,d,f).in-addr-servers.arpa.
32.104.172.in-addr.arpa.172.in-addr.arpa.(u,r,y,z,v,x,t,w).arin.net.
We pick b.root-servers.net, one of the 13 root servers (1), and ask it about 2.104.172.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask a.in-addr-servers.arpa where we learn that 172.in-addr.arpa is delegated to eight name servers, including u.arin.net (3), so we ask that one and get the following answer:
