We pick m.root-servers.net, one of the 13 root servers (1), and ask it about gunnismark.se and learn that se is delegated to nine name servers (2), so we ask c.ns.se where we learn that gunnismark.se is delegated to three name servers, including ns2.cust.port53.se (3), so we ask that one and get the following answer:
There are several hundred of domains that only use the IPv4 number 89.160.17.2.
Most of those use name server group 1 (example: nordprotekt.se, peppi.se and stinaodavid.se ). Worth noting is that half of the domains that use name server group 1 use only the IPv4 number 89.160.17.2.
