(c,d,e,a,b,h,f).nic.ch.
We pick h.root-servers.net, one of the 13 root servers (1), and ask it about b.nic.ch and learn that ch is delegated to seven name servers (2), so we ask c.nic.ch and get the following answer:
All of the three host names that point to the IP number 2001:620::5 point to the two IP numbers 2001:620::5 and 130.59.211.10 together, hereafter referred to as "IP group 1".
The IP number 130.59.211.10
All of the three host names that point to the IP number 130.59.211.10 point to IP group 1.
The name server b.nic.ch
All of the two domains that use the name server b.nic.ch use the seven name servers a, b, c, d, e, f and h.nic.ch together (example: ch and .ch ).
