We pick j.root-servers.net, one of the 13 root servers (1), and ask it about ns1.open.by and learn that by is delegated to six name servers (2), so we ask dns1.tld.tutby.com where we learn that open.by is delegated to three name servers, including ns3.open.by (3), so we ask that one and get the following answer:
Ns1.open.by is hosted on a server in Russian Federation even though the hostname implies Belarus.
The IP number 193.232.92.1
All of the four host names that point to the IP number 193.232.92.1 point only to that ip number.
