Subinterface in Windows

Question

Does anybody know how to add a network subinterface in Windows? Something like eth0:1 in Linux.

Answer 1

Like a second virtual adapter? of course. Since you haven't specified your version of Windows, I'll tell you the XP way. The only difference in configuration between XP and newer versions is how to get to your network connections, but I assume you know how to do that :)

• Right click on your connection in Network Connections and go to Properties, you will see a dialog like this:

• Ensure Internet Protocol (TCP/IP) is selected, and hit properties as shown above.
• If you aren't already using static addressing, grab your current network info from the command prompt using ipconfig /all and substitute it into this dialog:

• After you've filled in all the details, click the Advanced button at the bottom of the dialog shown above
• Near the top, under IP Addresses, click Add and specify the details of the new virtual interface in the dialog that pops up:

• Click OK on all windows, and you've got yourself a second IP bound to your network adapter!

Answer 2

I tried this, but one virtual interface is supposed to use DHCP and if I enable DHCP I cannot add more static IPs. Also I don't think it will support routing between these networks (I'm not sure of this, but I am going to try now).
