For some reason I cannot connect to the FTP, maybe I'm doing something wrong?

Can someone please tell me how do you connect to an ftp account?
I know the simpliest way, if I use the most common way - Internet Explorer, is to just type the host's ip:
For example:

ftp://70.98.54.28:2082 and then I should be asked my login name and password.
For some reason it says it can't establish a connection.
