We pick l.root-servers.net, one of the 13 root servers (1), and ask it about geenstijl.nl and learn that nl is delegated to eight name servers (2), so we ask ns3.dns.nl where we learn that geenstijl.nl is delegated to three name servers, including ns3.prolocation.net (3), so we ask that one and get the following answer:
Geenstijl.nl is a domain controlled by three domain name servers at prolocation.net having a total of five IP numbers. All five of them are on different IP networks. Incoming mail for geenstijl.nl is handled by four mail servers at googlemail.com and google.com having a total of 44 IP numbers. There are six duplicated IP numbers. Some of them are on the same IP network. Geenstijl.nl has two IP numbers (178.22.84.50, 2a00:d00:ff:219:81:173:64:50). Both are on different IP networks.
