We pick h.root-servers.net, one of the 13 root servers (1), and ask it about yahoo.ru and learn that ru is delegated to five name servers (2), so we ask d.dns.ripn.net where we learn that yahoo.ru is delegated to five name servers, including ns2.yahoo.com (3), so we ask that one and get the following answer:

We are missing the IP:s of one server: .. Yahoo.ru has two IP numbers (188.8.131.52, 184.108.40.206). Both are on different IP networks.
