If you need to create another domain name within your existing cPanel hosting account, you will need to set up what is called an Addon Domain. Not all packages allow for multiple domains, but check with Support if you have any questions regarding your package limits.
That's it! You can repeat the process for each domain/folder that you would like to associate. Please keep in mind that it may take up to 24 hours for the domain name to propagate throughout the Internet.
It is easier for WestHost to also manage your domain registration, but it is not required. You will want to contact your current registrar to verify that the DNS or Domain Name Servers for your domain are pointed to WestHost.
If you need to point your new addon domain name to the correct DNS, you will need to do so with your domain registrar.
that when you make DNS changes it can take 3-24 hours to propagate throughout the Internet.
