From this article, you will learn about Additional IPs with Virtualization Solutions.
The network setup of all virtualization solutions is similar. Depending on the software, you can use one or more variants:
If you want to use the bridged mode, and you need additional single IPs, you need to request virtual MAC addresses. You can get a MAC address for your additional single IP by going to your account. Simply login, select your server, and then go to the IPs tab. Here, you will see a button next to the additional single IP address. Clicking on that button will give the IP address a virtual MAC.
You can request virtual MAC addresses only for individual IPs, not for subnets.
|Linux KVM (also Proxmox) / Xen||x||x||x||–|
|OpenVZ (also Proxmox) / Virtuozzo||x1||x1||x1||x2|
- Applies only to veth devices
- Applies only to venet devices
- Requires RRAS (Routing and Remote Access) services
If you want to use IPs in a subnet with a virtualization solution that does not have routing capabilities, you need to use a VM to perform this function. You need to then route the subnet on this VM.
|Direct Routing||Router VM|
|Linux KVM (also Proxmox) / Xen||x||(x)|
|OpenVZ (also Proxmox) / Virtuozzo||x||(x)|
(x) – You can use a router VM, but it’s not necessary.
