DNS delegation of cepl.lu updated: Jun 18, 2013 9:44:49 PM
We pick k.root-servers.net, one of the 13 root servers (1), and ask it about cepl.lu and learn that lu is delegated to seven name servers (2), so we ask j.dns.lu where we learn that cepl.lu is delegated to three name servers, including ns2.pt.lu (3), so we ask that one and get the following answer:
Cepl.lu is a domain controlled by three domain name servers at pt.lu having a total of six IP numbers. Two of them are on the same IP network. Incoming mail for cepl.lu is handled by one mail server at csl.lu.
