How can I have multiple IP addresses assigned to a single NIC? I remember doing this on Unix way back when. Can it be done on Windows?

I know it CAN be done, because VMWare does it. I don't know HOW it's done though. – Grant Apr 30 '09 at 14:22

Yes, it can be done in Windows:

  1. Go to the Control Panel > Network Connections
  2. Right click on the Local Area Connection (or whichever network connection you want to add the 2nd IP Address) and click Properties
  3. Click on Internet Protocol (TCP/IP) in the connection box and click properties
  4. Enter the first IP address in the properties box
  5. Click Advanced
  6. Click Add under the IP Addresses box and enter the information for the 2nd IP Address
  7. Close all the boxes

Got it. Thanks. With one slight addition: 2.5 "and select Properties" – BIBD Apr 30 '09 at 14:33
Edited the answer to add it, thanks. – jeffl8n Apr 30 '09 at 14:38

Yes, it can be done.

On XP it was just a case of going into the "advanced" settings in the TCP/IP settings for the network.

I don't have Vista or any of the "server' variants of Windows to check against, but I'd be amazed if it wasn't possible.
