step query auth servers 1 glb01.snc1.tfbnw.net. . (m,k,c,e,i,h,g,a,d,f,b,j,l).root-servers.net. 2 glb01.snc1.tfbnw.net. net. (m,c,a,f,l,d,e,b,g,i,k,h,j).gtld-servers.net. 3 glb01.snc1.tfbnw.net. tfbnw.net. (b,a).ns.facebook.com.
We pick m.root-servers.net , one of the 13 root servers (1), and ask it about glb01.snc1.tfbnw.net and learn that net is delegated to 13 name servers (2), so we ask m.gtld-servers.net where we learn that tfbnw.net is delegated to two name servers, including b.ns.facebook.com (3), so we ask that one and get the following answer:
