DNS delegation of 3cx.dk updated: Jun 20, 2013 3:34:05 AM
We pick l.root-servers.net, one of the 13 root servers (1), and ask it about 3cx.dk and learn that dk is delegated to six name servers (2), so we ask p.nic.dk where we learn that 3cx.dk is delegated to two name servers, including ns2.eurodns.com (3), so we ask that one and get the following answer:
3cx.dk 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.dk is handled by one mail server at 3cx.com having a total of twelve IP numbers. Some of them are on the same IP network. 3cx.dk has one IP number (188.8.131.52), but the reverse is 80-92-65-144.ip.dclux.com.
About one in six of them use name server group 2 (example: 770.fr, drnatura.se and dsresearch.nl ). Worth noting is that eleven percent of the domains that use name server group 2 point only to the IP number 184.108.40.206.
The two name servers ns1 and ns2.eurodns.com together
There are several thousand of domains that use name server group 2.
