Rod is correct.

When you sign up for a hosting account, your host will provide you with the FTP login details, including the server path, username and password, and whether the connection is SSL Auth or just plain FTP.

If your domain does not currently resolve to the Server's IP address, your host will tell you how to handle this, and probably give a name (NOT an IP address) such as servername.net or servername.com .

In any event, the "welcome" message you should have received from the host will have all the FTP instructions.
