# Adding an IP alias to Windows

There may be times when you have multiple IPs assigned to a single Windows server with only one Network Interface Card (NIC).

How do you add those additional IPs to Windows? The following steps will guide you through the process.

**Note: you can only have one default gateway active at a time**

1. Using your Start Menu's Search feature, Search Windows for "**ncpa.cpl**" and press Enter.![](https://cdn.document360.io/d809f158-d4f4-47ff-83d4-18d9c9f7a04d/Images/Documentation/Screenshot%202026-06-06%20at%201.42.17%E2%80%AFpm.jpg)

2. Right-click on the Adapter that you wish to modify and select **'Properties'**![](https://cdn.document360.io/d809f158-d4f4-47ff-83d4-18d9c9f7a04d/Images/Documentation/Screenshot%202026-06-06%20at%201.44.16%E2%80%AFpm.jpg)
