We pick g.root-servers.net, one of the 13 root servers (1), and ask it about icb.co.uk and learn that uk is delegated to eleven name servers (2), so we ask nsa.nic.uk where we learn that icb.co.uk is delegated to four name servers, including ns4.icb.co.uk (3), so we ask that one and get the following answer:
