We pick c.root-servers.net, one of the 13 root servers (1), and ask it about k.to and learn that to is delegated to five name servers (2), so we ask to.cctld.authdns.ripe.net where we learn that k.to is delegated to three name servers, including ns3.keek.com (3), so we ask that one and get the following answer:
K.to is a domain controlled by three domain name servers at keek.com. All three of them are on different IP networks. Incoming mail for k.to is handled by one mail server also at keek.com. We are missing the IP:s of one server: mail1.keek.com. K.to has one IP number (66.207.203.72), which also has a corresponding reverse pointer.
K.to is hosted on a server in Toronto, ON, Canada even though the hostname implies Tonga.
The name server ns3.keek.com
All of the about twenty domains that use the name server ns3.keek.com use the three name servers ns1, ns2 and ns3.keek.com together, hereafter referred to as "name server group 1", (example: vuzilla.com, keeke.biz and keek.us ).
