130.in-addr.arpa..(g,m,i,d,j,a,l,e,c,k,b,h,f).root-servers.net.
230.in-addr.arpa.in-addr.arpa.(a,c,d,e,f,b).in-addr-servers.arpa.
We pick g.root-servers.net, one of the 13 root servers (1), and ask it about 30.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:
