We pick k.root-servers.net, one of the 13 root servers (1), and ask it about klikbca.com and learn that com is delegated to 13 name servers (2), so we ask k.gtld-servers.net where we learn that klikbca.com is delegated to four name servers, including ns2.cbn.net.id (3), so we ask that one and get the following answer:
Klikbca.com is a domain controlled by five domain name servers at net.id having a total of seven IP numbers. Some of them are on the same IP network. Incoming mail for klikbca.com is handled by three mail servers at klikbca.com themselves. Two of them are on the same IP network.
