DNS delegation of citco.ch updated: May 19, 2013 8:21:42 PM
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.
There are about twenty domains that only use the IPv4 number 184.108.40.206.
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 220.127.116.11.
Three of them are under the tld "net".
