step query auth servers 1 citysearch.com.s7b2.psmtp.com. . (f,a,k,e,b,d,c,h,j,l,g,m,i).root-servers.net. 2 citysearch.com.s7b2.psmtp.com. com. (h,m,b,l,k,a,c,e,f,i,d,j,g).gtld-servers.net. 3 citysearch.com.s7b2.psmtp.com. psmtp.com. (ns4,ns1,ns3,ns2).google.com.
We pick f.root-servers.net , one of the 13 root servers (1), and ask it about citysearch.com.s7b2.psmtp.com and learn that com is delegated to 13 name servers (2), so we ask h.gtld-servers.net where we learn that psmtp.com is delegated to four name servers, including ns4.google.com (3), so we ask that one and get the following answer:
