The below links/URLs are generic for all cPanel servers. If you are ever unsure of the port to use, you can simply add the respected service to the end of your URL like so:
http://yourdomain.com/cpanel
http://yourdomain.com/whm
http://yourdomain.com/webmail
Note: If your DNS (name servers) have not yet been set or have very recently been set due to a recent migration or installation, you may replace “yourdomain.com” in the above examples with your main server IP address provided to you in your welcome email.
