Two IP, One NIC?

I know that it's possbile to have two statics IP on one physical NIC. But is it possbile to have to dynamic IP numbers on one physical NIC? My ISP allows me to have five ip's. So I wonder if I can have two ip's on one nic? I'm running windows 2003 server.

Is there any negative side on having two ip on one nic instead of having two nics?

From the systems that I have worked on the simple answer is no, as the DHCP server uses the MAC address of th NIC to uniquely identify the card.

The real question is why you would want to do this in the first place?

why don't you use two nic's? I use two of them, one for my internet connection and one for my local network. I think I could use both of them for internet but I don't know how would windows use such two internet connections.

Or install the MS Loopback adapter for a virtual NIC.

You can set one IP dynamic and one IP static if you have XP pro, so set one static and all is well. The other IP you configure under "alternate configuration"
