We pick m.root-servers.net, one of the 13 root servers (1), and ask it about agroteh.biz and learn that biz is delegated to six name servers (2), so we ask c.gtld.biz where we learn that agroteh.biz is delegated to two name servers, including ns2.valuehost.ru (3), so we ask that one and get the following answer:
Agroteh.biz is a domain controlled by three domain name servers at valuehost.ru. All three of them are on different IP networks. Incoming mail for agroteh.biz is handled by three mail servers at googlemail.com and agroteh.biz having a total of 28 IP numbers. There are nine duplicated IP numbers. Some of them are on the same IP network.
