We pick a.root-servers.net, one of the 13 root servers (1), and ask it about www.lu and learn that lu is delegated to seven name servers (2), so we ask p.dns.lu where we learn that www.lu is delegated to two name servers, including ns1.restena.lu (3), so we ask that one and get the following answer:
Www.lu is a domain controlled by three domain name servers at restena.lu having a total of six IP numbers. Some of them are on the same IP network. Www.lu has one IP number (158.64.1.39), but the reverse is faramir.restena.lu.
Twelve of them use the name server ns1.restena.lu (example: asti.lu ). Worth noting is that eleven of the domains that use the name server ns1.restena.lu point to the IP number 158.64.1.39.
Eleven of them use the name server ns3.restena.lu. Worth noting is that eight of the domains that use the name server ns3.restena.lu point to the IP number 158.64.1.39.
There are more than two hundred domains that use the name server ns1.restena.lu.
Eleven of those point to the IP number 158.64.1.39. Worth noting is that eleven of the host names that point to the IP number 158.64.1.39 use the name server ns1.restena.lu.
