(ns3,ns2,ns1,ns4,ns5).yahoo.com.
We pick l.root-servers.net, one of the 13 root servers (1), and ask it about actionality.com and learn that com is delegated to 13 name servers (2), so we ask f.gtld-servers.net where we learn that actionality.com is delegated to five name servers, including ns3.yahoo.com (3), so we ask that one and get the following answer:
Actionality.com is a domain controlled by five domain name servers at yahoo.com. All five of them are on different IP networks. Incoming mail for actionality.com is handled by four mail servers also at yahoo.com. Some of them are on the same IP network. Actionality.com has one IP number (217.188.214.99), but the reverse is ?.
