We pick d.root-servers.net, one of the 13 root servers (1), and ask it about ccpe.lu and learn that lu is delegated to seven name servers (2), so we ask i.dns.lu where we learn that ccpe.lu is delegated to two name servers, including ns2.restena.lu (3), so we ask that one and get the following answer:
Ccpe.lu is a domain controlled by three domain name servers at restena.lu having a total of three IP numbers. Some of them are on the same IP network. We are missing the IP:s of three servers: ns2.restena.lu, ns1.restena.lu and ns3.restena.lu. Incoming mail for ccpe.lu is handled by two mail servers also at restena.lu having a total of two IP numbers. Both are on the same IP network. We are missing the IP:s of one server: smtpgate1.restena.lu.
