DNS delegation of 3cx.cz updated: May 23, 2013 1:23:43 PM
We pick a.root-servers.net, one of the 13 root servers (1), and ask it about 3cx.cz and learn that cz is delegated to five name servers (2), so we ask c.ns.nic.cz where we learn that 3cx.cz is delegated to two name servers, including ns2.eurodns.com (3), so we ask that one and get the following answer:
3cx.cz is a domain controlled by two domain name servers at eurodns.com having a total of four IP numbers. Some of them are on the same IP network. Incoming mail for 3cx.cz is handled by one mail server at 3cx.com having a total of 15 IP numbers. Some of them are on the same IP network. 3cx.cz has one IP number (188.8.131.52), but the reverse is 80-92-65-144.ip.dclux.com.
