I am trying to set private nameserver for my domain. For this, I have entered ns1 and ns2 entries in the simple zone editor under cpanel. Also I have added Host entry in godaddy account and updated my nameserver there. So now if I check whois information, correct information is being displayed. ( I mean ns1.domainname.com and ns2.domainname.com are being displayed as nameserver ) But when I do DNS lookup under site like network-tools.com, there it will show the original server and not my private nameserver. For example: network-tools.com/default.asp?prog=dnsrec&host=agro-lanka.org under the "server", it is showing "ns1.ndx20.com" which is the original server. So I am not able to hide the original nameserver( this is just an example, not my site, but similar thing is happening to me ) But if I check for others' website which has set private server, there own private nameserver is being shown under "server" entry. For example: network-tools.com/default.asp?prog=dnsrec&host=cobithost.net here you will see that it is showing "cobithost" under "server" So can anybody tell me what is the problem in the my case?
