We pick m.root-servers.net, one of the 13 root servers (1), and ask it about www.cat and learn that cat is delegated to eight name servers (2), so we ask switch.nic.cat where we learn that www.cat is delegated to three name servers, including ns8.knipp.net (3), so we ask that one and get the following answer:

The name server ns4.knipp.de
Three quarter of the about fourty domains that use the name server ns4.knipp.de use the three name servers ns0, ns4 and ns7.knipp.de together (example: 5.253.195.in-addr.arpa, 48.253.195.in-addr.arpa and 62.138.195.in-addr.arpa ).

The IP number 195.253.31.17
There are seven host names that point to the IP number 195.253.31.17.
