We pick l.root-servers.net, one of the 13 root servers (1), and ask it about albumyahoo.com and learn that com is delegated to 13 name servers (2), so we ask h.gtld-servers.net where we learn that albumyahoo.com is delegated to five name servers, including ns7.yahoo.com (3), so we ask that one and get the following answer:
Albumyahoo.com is a domain controlled by five domain name servers at yahoo.com. All five of them are on different IP networks. Incoming mail for albumyahoo.com is handled by one mail server at .. We are missing the IP:s of one server: .. Albumyahoo.com has two IP numbers (68.180.206.184, 98.139.102.145). Both are on different IP networks.
