How to add a VPC private IP to a VPS

Step 1: Access the Manage Panel

Go to the Manage Panel of your VPS and select the Network tab.

Step 2: Add VPS to VPC

Scroll down to the VPC section within the page.

Add your VPS to the VPC. This action will create a VPC IP, such as 192.168.0.80 in this example.

Note: In most operating systems, the interface will automatically add itself. However, in Ubuntu, the interface is attached to the server, but the configuration must be completed manually.

Step 3: Identify the New Interface

Use the following command to list network interfaces and find the new one (often named ens7, but this may vary):

ip a s

Step 4: Note the MAC Address

Identify and note the MAC address of the new interface.

Step 5: Edit Netplan Configuration

Open /etc/netplan/50-cloud-init.yaml with your preferred text editor.

Step 6: Add Interface Configuration

Add the following configuration for your server.

You ONLY need to add things under the new interface you are adding (ens7) in our case.
In this example, the MAC for the new interface is fa:16:3e:7a:84:21 (replace with your actual MAC address):

network:
    version: 2
    ethernets:
        ens3:
            dhcp4: true
            match:
                macaddress: fa:16:3e:46:3f:b1
            set-name: ens3
        ens7: 
            dhcp4: true
            match:
                macaddress: fa:16:3e:7a:84:21
            set-name: ens7

Step 7: Apply Netplan Configuration

Run the following command to apply the new network settings:

sudo netplan apply

Step 8: Verify IP Assignment

Finally, use ip a s to confirm that the new VPC IP is assigned to the interface.
