How to Adding IP Addresses to Windows Server

Using netsh command.

The order prompt method is the fastest and we suggest it first. To add IP addresses to a Windows VPS or Windows Server, first open the order Prompt at Start > Run > cmd.

Enter the order for each new IP address to add to the system:

netsh interface ipv4 adding address “Local Area Connection” 192.168.1.2 255.255.255.0
Change “192.168.1.2” to your additional IP. The subnet mask is usually 255.255.255.0 – Please contact us for confirmation of netmask before doing this.

Adding IP Addresses to Windows.

Navigate to the Control Panel

Click on Network & Internet

Network and Sharing Center

And Change Adapter Settings

Select Ethernet and right-click then choose TCP/IPV4 and clicks Properties.

Checking that your server is configured to use a specific IP address, netmask, and gateway.

Click Advanced… and Add to enter your additional IP addresses and gateway. In most cases, the same Subnet mask as the primary IP is used.

Once all the IP addresses are configured, press OK through all of the settings windows. The IP addresses are now connected to the system.
