I just registered a domain on namecheap.com and I don't know the nameservers that my host has (hosts DP name is xpit). Can anyone tell me how I can put my new domain into Cpanel or WHM successfully please? Thanks
Depending on your host, your domain may need to reside on the hosts nameservers before it will allow you to add it to your WHM. I would contact your hosts support to get the information. Otherwise, if you know another domain hosted at the same host you can do a whois lookup to find out what nameservers are being used and update it on Namecheap
