DNS delegation of cctld.cz updated: May 19, 2013 9:28:43 PM
We pick b.root-servers.net, one of the 13 root servers (1), and ask it about cctld.cz and learn that cz is delegated to five name servers (2), so we ask a.ns.nic.cz where we learn that cctld.cz is delegated to five name servers, including ns4.gransy.com (3), so we ask that one and get the following answer:
Cctld.cz is a domain controlled by five domain name servers at gransy.com having a total of six IP numbers. Two of them are on the same IP network. Incoming mail for cctld.cz is handled by two mail servers also at gransy.com having a total of two IP numbers. There are two duplicated IP numbers. Both are on different IP networks. Cctld.cz has two IP numbers (220.127.116.11, 2001:1528:137::c). Both are on different IP networks.
