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