We pick b.root-servers.net, one of the 13 root servers (1), and ask it about yahoo.bh and learn that bh is delegated to four name servers (2), so we ask ns4.batelco.com.bh where we learn that yahoo.bh is delegated to five name servers, including ns2.yahoo.com (3), so we ask that one and get the following answer:
Yahoo.bh is a domain controlled by five domain name servers at yahoo.com. All five of them are on different IP networks. Yahoo.bh has two IP numbers (77.238.178.122, 87.248.120.148). Both are on different IP networks.
