I can currently add CNAME records pointing subdomains to other places as cpanel's dns area allows me to specify a subdomain hostname. However, how can I create a CNAME record for the main domain and not a subdomain? I tried parking the domain into cpanel and then using www as the hostname in the CNAME record but that is not working.
What are you actually trying to accomplish here? The main domain shouldn't be a CNAME record but an IP address. Is there a reason you would not use an IP address for the main domain and want to use a CNAME?
