1250.in-addr.arpa..(g,e,d,c,a,h,b,f,l,j,m,i,k).root-servers.net.
2250.in-addr.arpa.in-addr.arpa.(a,f,e,c,d,b).in-addr-servers.arpa.
We pick g.root-servers.net, one of the 13 root servers (1), and ask it about 250.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask a.in-addr-servers.arpa and get the following answer:
