I have one shared hosting temporary without domain name. I will do the migration later.

I would like to upload some files onto this shared hosting for viewing purpose. The problem is I not able to figure out how to access to the file that I uploaded as there is no domain name in there.

How can I access to the file with the shared ip?

On cPanel and a lot of other Linux based webservers you can access as http://IPADDRESS/~username/

its worked. Thanks for that.
