I'm not sure I fully understand your question, but I'll offer you some answers and hope they help.
If you don't have a domain name on the server, you can use http://IP.ADD.RESS (the IP address) to access it.
If you want to develop a system on one server and deliver the content through a different one, you could use and <b>iframe</b> to pull the remote content in. This will cause SEO problems later, so it should only be used in a test environment.
