DNS delegation of ong.lu updated: May 22, 2013 7:33:37 PM
We pick c.root-servers.net, one of the 13 root servers (1), and ask it about ong.lu and learn that lu is delegated to seven name servers (2), so we ask j.dns.lu where we learn that ong.lu is delegated to three name servers, including ns2.restena.lu (3), so we ask that one and get the following answer:
Ong.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. Incoming mail for ong.lu is handled by two mail servers also at restena.lu having a total of three IP numbers. Two of them are on the same IP network.
