dmin.us.
(ns1,ns4,ns3,ns2).linode.com.
We pick l.root-servers.net, one of the 13 root servers (1), and ask it about a.dmin.us and learn that us is delegated to six name servers (2), so we ask a.cctld.us where we learn that dmin.us is delegated to four name servers, including ns1.linode.com (3), so we ask that one and get the following answer:
A.dmin.us is a domain controlled by five domain name servers at linode.com having a total of ten IP numbers. All ten of them are on different IP networks. Incoming mail for a.dmin.us is handled by one mail server at dmin.us. A.dmin.us has one IP number (69.164.204.235), which is the same as for dmin.us, but the reverse is geoha.ms.
