We pick g.root-servers.net, one of the 13 root servers (1), and ask it about c.ns.tk and learn that tk is delegated to four name servers (2), so we ask a.ns.tk and get the following answer:
All of the one host names that point to the IP number 2001:678:58::1 point to the two IP numbers 2001:678:58::1 and 194.0.40.1 together, hereafter referred to as "IP group 1".
The IP number 194.0.40.1
All of the one host names that point to the IP number 194.0.40.1 point to IP group 1.
