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:
- Bridged
- Routed
- NAT
Single IPs
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 Robot account. Simply login, select your server, and then go to the IPs tab. Here, you will see a small 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.
| Bridged | Routed | NAT | Special | |
|---|---|---|---|---|
| Linux KVM (also Proxmox) / Xen | x | x | x | - |
| OpenVZ (also Proxmox) / Virtuozzo | x1 | x1 | x1 | x2 |
| VMware ESXi | x | |||
| Microsoft Hyper-V | x | x3 | x3 |
- Applies only to veth devices
- Applies only to venet devices
- Requires RRAS (Routing and Remote Access) services
Subnets
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) |
| VMware ESXi | x | |
| Microsoft Hyper-V | x | (x) |
(x) - You can use a router VM, but it's not necessary.
