Add Additional IPs to a Windows Server 2008

Learn how to add an IP address that you have ordered from the 1&1 Control Panel to your Windows Server 2008.

Dedicated Servers come with one IP address. It is possible to order additional IP addresses through the 1&1 Control Panel. When ordering additional IP addresses, 1&1 ensures that the IP is set to route correctly to your individual server however it is still necessary to add this IP address to the operating system to ensure the server knows which additional IPs are available to use.
