118.in-addr.arpa..(h,i,m,f,j,k,b,a,d,c,e,g,l).root-servers.net.
218.in-addr.arpa.in-addr.arpa.(e,f,c,a,b,d).in-addr-servers.arpa.
318.in-addr.arpa.18.in-addr.arpa.(bitsy,w20ns,strawb).mit.edu.
We pick h.root-servers.net, one of the 13 root servers (1), and ask it about 18.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask e.in-addr-servers.arpa where we learn that 18.in-addr.arpa is delegated to three name servers, including bitsy.mit.edu (3), so we ask that one and get the following answer:
