We pick k.root-servers.net, one of the 13 root servers (1), and ask it about pil.dk and learn that dk is delegated to six name servers (2), so we ask p.nic.dk where we learn that pil.dk is delegated to three name servers, including ns2.pil.dk (3), so we ask that one and get the following answer:
Pil.dk is a domain controlled by three domain name servers at pil.dk themselves having a total of six IP numbers. Some of them are on the same IP network. Incoming mail for pil.dk is handled by two mail servers also at pil.dk having a total of three IP numbers. All three of them are on different IP networks. Pil.dk has one IP number (195.41.47.3), but the reverse is dijkstra.pil.dk.
All of the several hundred of domains that use the mail server mx02.pil.dk use the two mail servers mx02 and mx03.pil.dk together, hereafter referred to as "mail server group 1", (example: holstweb.dk, hald.nu and ecrf.dk ).
