Delegation
step query auth servers 1 youtube.com. . (b,f,m,h,c,k,l,g,e,j,i,a,d).root-servers.net. 2 youtube.com. com. (f,b,d,c,g,l,e,k,a,j,i,h,m).gtld-servers.net. 3 youtube.com. youtube.com. (ns4,ns3,ns2,ns1).google.com.
We pick b.root-servers.net , one of the 13 root servers (1), and ask it about youtube.com and learn that com is delegated to 13 name servers (2), so we ask f.gtld-servers.net where we learn that youtube.com is delegated to four name servers, including ns4.google.com (3), so we ask that one and get the following answer:
