There are a few ways to log into cPanel. It all depends on if the domain name has propagated yet. If you purchased a new account the details of temporary IP addresses will be emailed to you within our welcome email. You then need to type the following information into the address bar of your web browser.
http://your-ip-address/cpanel/ (Example: http://1.2.3.4/cpanel/)
An alternative way is to log in with the IP address and the port number for cPanel, which is set as default at 2082.
http://your-ip-address:2082/ (Example: http://1.2.3.4:2082/)
If the Domain Name has already propagated, then you can use the domain name to log into cpanel. Below is an example.
http://www.yourdomainname.com/cpanel/
or
http://www.yourdomainname.com:2082/
