We pick c.root-servers.net, one of the 13 root servers (1), and ask it about open.by and learn that by is delegated to six name servers (2), so we ask dns3.tld.tutby.com where we learn that open.by is delegated to three name servers, including ns1.open.by (3), so we ask that one and get the following answer:
Open.by is a domain controlled by three domain name servers at open.by themselves. Two of them are on the same IP network. Incoming mail for open.by is handled by two mail servers also at open.by. Both are on the same IP network. Open.by has one IP number (93.84.119.227), but the reverse is dc2.ok.by.
All of the more than hundred domains that use the two name servers ns2 and s1.open.by together, hereafter referred to as "name server group 1", point only to the IP number 193.232.92.29 (example: plc.by, newlife.by and kemping.by ).
