We pick l.root-servers.net, one of the 13 root servers (1), and ask it about coghlan.net and learn that net is delegated to 13 name servers (2), so we ask j.gtld-servers.net where we learn that coghlan.net is delegated to two name servers, including ns2.amenworld.com (3), so we ask that one and get the following answer:
Coghlan.net is a domain controlled by two domain name servers at amenworld.com having a total of four IP numbers. Some of them are on the same IP network. Incoming mail for coghlan.net is handled by three mail servers at messagelabs.com and coghlan.net having a total of ten IP numbers. Some of them are on the same IP network. We are missing the IP:s of one server: mx2.coghlan.net. Coghlan.net has one IP number (217.28.130.235), but no corresponding reverse pointer.
