Change Name server

Dear All,

I want to know, can we change nameserver from centos-webpanel.com to others?
Example, default is ns1.centos-webpanel.com. Can we change to ns1.example.com?

you can use any nameserves on your server, this depends on your domain and domain registrar.

Can you tell me how to change name server in centos-webpanel?
Because I really don't know how to change name server in the application.

you need to edit nameservers in nameserver section of the CWP and if you are using your own server as dns server then you will also need to add entry's for your nameservers ns1 and ns2 in zone file.
