We pick m.root-servers.net, one of the 13 root servers (1), and ask it about citco.ch and learn that ch is delegated to seven name servers (2), so we ask c.nic.ch where we learn that citco.ch is delegated to two name servers, including dns2.zeiningen.com (3), so we ask that one and get the following answer:
All of the 15 domains that use the primary name server dns1.zeiningen.com use name server group 1. Worth noting is that all of the domains that use name server group 1 use the primary name server dns1.zeiningen.com.
The two name servers dns1 and dns2.zeiningen.com together
There are 15 domains that use name server group 1.
All of those use the primary name server dns1.zeiningen.com. Worth noting is that all of the domains that use the primary name server dns1.zeiningen.com use name server group 1.
All of them use only the IPv4 number 89.110.146.150. Worth noting is that three quarter of the domains that only use the IPv4 number 89.110.146.150 use name server group 1.
There are about twenty domains that only use the IPv4 number 89.110.146.150.
Two thirds of those use the two mail servers mail1 and mail3.zeiningen.com together, hereafter referred to as "mail server group 1". Worth noting is that all of the domains that use mail server group 1 use only the IPv4 number 89.110.146.150.
Three of them are under the tld "net".
The two mail servers mail1 and mail3.zeiningen.com together
There are 14 domains that use mail server group 1.
