1251.in-addr.arpa..(f,k,d,m,e,c,h,l,b,i,j,a,g).root-servers.net.
2251.in-addr.arpa.in-addr.arpa.(c,b,d,e,a,f).in-addr-servers.arpa.
We pick f.root-servers.net, one of the 13 root servers (1), and ask it about 251.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask c.in-addr-servers.arpa and get the following answer:
