We pick c.root-servers.net, one of the 13 root servers (1), and ask it about indextools.com and learn that com is delegated to 13 name servers (2), so we ask k.gtld-servers.net where we learn that indextools.com is delegated to five name servers, including ns2.yahoo.com (3), so we ask that one and get the following answer:
Indextools.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 indextools.com is handled by four mail servers also at yahoo.com. Some of them are on the same IP network. Indextools.com has two IP numbers (68.180.206.184, 98.139.102.145). Both are on different IP networks.
