Under Internet protocol for TCP/IP on your network adapter, click "advanced"

There you can add as many ips as you want, simply insert ip address and then subnet mask.
With the "MS Loopback" NIC.
Open Control Panel, start the Add/Remove Hardware wizard.
Confirm that the hardware has been installed.
In the next screen, choose "Add new hardware" from the dropdown list.
In the next screen, choose "Install hardware manually (for advanced users)"
In the next screen, choose "Network Adapter"
In the next screen, choose Microsoft as "Manufacturer", and pick the "Microsoft Loopback Adapter".
Install the "adapter", and it will appear as a regular NIC.

Yes, you can create the loopback adapter like oBdA said. But, let me ask why you want to do that? Maybe we can suggest another path to whatever you need to do.
Free Tool: Subnet Calculator

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

I am using IIS.  I want my ftp server, my web server, and my file server (all the same physical computer with one NIC) to all be accessible from the web using different IPs.  So I want to be able to hit a page on my web server using and access my ftp from  (both of those IPs are external).

I know i can do this with virtual server but i dont want to consume the resources required to have another OS installed.

You know FTP uses a different port, dont you? So you can have both answering on the same IP. But, besides, you can set more than one IP on the same interface, without using the loopback adapter.

I dont see how you will map those address to be visible on the internet. You will need some NAT elsewhere.

thanks guys,

That was what i was looking for dognamedmoses but i have one unanswered aspect.  If i have some IP addresses that are assigned to me via dhcp, and i add all those IPs to one NIC, will they all lead to my computer from the outside world?
Renato Montenegro RusticiIT SpecialistCommented:
You dont need to add them. You must use your ISP address as the destination.
Renato Montenegro RusticiIT SpecialistCommented:
But this address changes when you reconnect. So its best to rent a web site. You can use DynDNS to map your ever-changing address to a name.
