We pick d.root-servers.net, one of the 13 root servers (1), and ask it about yahoo.be and learn that be is delegated to five name servers (2), so we ask prague.ns.dns.be where we learn that yahoo.be is delegated to five name servers, including ns3.yahoo.com (3), so we ask that one and get the following answer:
Yahoo.be is a domain controlled by three domain name servers at yahoo.com. All three of them are on different IP networks. Incoming mail for yahoo.be is handled by one mail server at yahoodns.net having a total of two IP numbers. Both are on different IP networks. Yahoo.be has two IP numbers (68.180.206.184, 98.139.102.145). Both are on different IP networks.
Yahoo.be is ranked #4 world wide as yahoo.com and is hosted on two servers in Sunnyvale, CA, United States even though the hostname implies Belgium. It has gained 864 inlinks over a period of 18 years.
The two IP numbers 68.180.206.184 and 98.139.102.145 together
There are several thousand of host names that point to the two IP numbers 68.180.206.184 and 98.139.102.145 together, hereafter referred to as "IP group 1".
Most of those use the five name servers ns1, ns2, ns3, ns4 and ns5.yahoo.com together, hereafter referred to as "name server group 1", (example: yahooespaqol.com, yahoomxail.com and yahoo68.com ). Worth noting is that half of the domains that use name server group 1 point to IP group 1.
