We pick c.root-servers.net, one of the 13 root servers (1), and ask it about ahoos.com and learn that com is delegated to 13 name servers (2), so we ask d.gtld-servers.net where we learn that ahoos.com is delegated to two name servers, including ns1.yahoo.com (3), so we ask that one and get the following answer:
Ahoos.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 ahoos.com is handled by one mail server at .. We are missing the IP:s of one server: .. Ahoos.com has two IP numbers (68.180.206.184, 98.139.102.145). Both are on different IP networks.
