A virtual machine (VM) on a virtual network can be accessed from the Internet using a floating IP address. This floating IP is taken from the physical network and linked to the VM’s private IP address. The VM uses both IP addresses at the same time:
- Private IP: For communicating with other VMs in the same virtual network.
- Floating IP: For being accessed from the Internet or other public networks.
The VM’s operating system doesn’t know about the floating IP—it only works with the private IP.
To create a floating IP address and assign it to a virtual machine
1. Go to the Floating IPs screen and click Add Floating IP.
2. In the Add Floating IP Address window:
- Choose a physical network to get the floating IP from.
- Select the VM’s network interface with its private IP.
3. Click Add.
To re-assign a floating IP address to another virtual machine
1. Click the ellipsis icon (three dots) next to the floating IP address, then choose Unassign.
2. Once the VM name disappears in the Assigned to column, click the ellipsis icon again, and then select Assign.
3. Click the ellipsis icon again and select Assign.
4. In the Assign Floating IP Address window, pick the VM’s network interface with its private IP.
5. Click Assign.
To remove a floating IP address
1. Unassign it from a virtual machine. Click the ellipsis icon next to the floating IP address, and then click Unassign.
2. Click the ellipsis icon again, and then select Delete.
Here is one more method we have to Delete floating IP Address. Select the Floating IP and click on Delete.
