step query auth servers 1 glb01.sf2p.tfbnw.net. . (c,m,b,j,d,k,a,l,e,g,i,h,f).root-servers.net. 2 glb01.sf2p.tfbnw.net. net. (i,l,e,f,m,a,d,k,c,b,g,j,h).gtld-servers.net. 3 glb01.sf2p.tfbnw.net. tfbnw.net. (b,a).ns.facebook.com.
We pick c.root-servers.net , one of the 13 root servers (1), and ask it about glb01.sf2p.tfbnw.net and learn that net is delegated to 13 name servers (2), so we ask i.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:
