We pick d.root-servers.net, one of the 13 root servers (1), and ask it about arpa.mil and learn that mil is delegated to six name servers (2), so we ask con1.nipr.mil and get the following answer:
Arpa.mil is a domain controlled by two domain name servers at darpa.mil. Both are on the same IP network. Incoming mail for arpa.mil is handled by two mail servers also at darpa.mil. Both are on the same IP network.
