We pick c.root-servers.net, one of the 13 root servers (1), and ask it about ducatiklub.hu and learn that hu is delegated to seven name servers (2), so we ask ns-com.nic.hu where we learn that ducatiklub.hu is delegated to two name servers, including ns1.ducatiklub.motorinfo.hu (3), so we ask that one and get the following answer:
Ducatiklub.hu is a domain controlled by two domain name servers at motorinfo.hu. Both are on different IP networks. Incoming mail for ducatiklub.hu is handled by five mail servers at googlemail.com and google.com having a total of 49 IP numbers. There are 18 duplicated IP numbers. Some of them are on the same IP network. Ducatiklub.hu has one IP number (87.229.7.67), but the reverse is mail.zylon.hu.
