How to add an additional IP on your Windows server
Kort antwoord
Add the extra IP address to your network adapter's IPv4 properties in Network and Sharing Center. The IP must already be assigned to your server package before you can configure it.
The steps below use standard Windows networking dialogs that are consistent across current Windows Server releases, so the same steps apply whichever supported version you're running.
Add a second IP
Open Control Panel
Search for "Control Panel" from the Start menu and open it.
Go to Network and Internet
Open Network and Sharing Center
Select your active network adapter
Click through to your active adapter (for example "Ethernet" or "Onboard LAN").
Open IPv4 properties
Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
Open Advanced settings
Click Advanced in the bottom right of the dialog.
Add the extra IP address
Under IP addresses, click Add and enter your additional IP address and the subnet mask shown for that IP.
Save your settings
Click OK on each screen to apply and save the changes.
