We pick b.root-servers.net, one of the 13 root servers (1), and ask it about qa and learn that qa is delegated to eleven name servers (2), so we ask a.registry.qa and get the following answer:
Qa (the tld of Qatar) is a domain controlled by eleven domain name servers at registry.qa having a total of 14 IP numbers. Some of them are on the same IP network.
