Can I put my name servers on cprapid.com (ns1.cprapid.com)?
No, you must use a domain that you control the DNS for. cprapid.com is owned and controlled by cPanel. It is used to ensure that all new installations of cPanel/WHM have a hostname that resolves to the server, which allows the server to obtain a free hostname SSL certificate. More information about this can be found in our documentation linked below.
