How to create multiple ip addresses on single server

I mainly use AWS for this and to get multiple IP addresses for my server. I would acquire the ip addresses within AWS then associate them with the server instance or network interface.

I think this tutorial will help you no need for IIS or any additional setup ( Configuring additional IP addresses on centos ) https://contabo.com/?show=tutorials&tutorial=configuring-additional-ip-addresses

You don't really need to have multiple ip addresses to host multiple sites. Just virtual hosts för each site.

If it's a more permanent solution i'd use this guide that does it all and lets you manage the sites with a nice gui.

If you really need to have one ip per site then I'd set up a VM with lamp or lemp for each.

That is of course if you host the pages on a local server and not in the cloud.
