We pick e.root-servers.net, one of the 13 root servers (1), and ask it about nic.eu and learn that eu is delegated to six name servers (2), so we ask si.dns.eu where we learn that nic.eu is delegated to four name servers, including ns3.eurid.eu (3), so we ask that one and get the following answer:
Nic.eu is a domain controlled by four domain name servers at eurid.eu having a total of seven IP numbers. All seven of them are on different IP networks. Nic.eu has two IP numbers (2001:67c:40:1::210, 91.220.191.210). Both are on different IP networks.
Seven of the eight domains that use the name server ns4.eurid.eu use the four name servers ns1, ns2, ns3 and ns4.eurid.eu together, hereafter referred to as "name server group 1".
The four name servers ns1, ns2, ns3 and ns4.eurid.eu together
Three of the seven domains that use name server group 1 point to the two IP numbers 2001:67c:40:1::212 and 91.220.191.212 together.
