A failover IP/subnet is an additional IP/subnet that you can switch from one server to another. You can order it for any Hetzner dedicated root server, and you can switch it to any other Hetzner dedicated root server, regardless of location.
- You can only switch a failover subnet as a whole; you can't switch single IPs from the subnet individually.
- You need to add the failover IP/subnet to the network configuration of all servers you want to use it on.
The prices for failover IP/Subnet can be found here.
To order an additional IP/subnet, please log into Robot, select
Servers from the menu on the left, and then select the server you want the IPs for. The first tab (that should automatically be open) is called
IPs. At the bottom of this tab page, you can click on the link
Order additional IPs/Nets. You will now see an overview of the IPs you can order, along with the price for each option.
We only allocate IPs if their use conforms to RIPE guidelines. This means we require a valid technical reason for why you need the IPs.
We allocate IP addresses during normal office hours: Monday-Friday, 7:30am-4:30pm CE(S)T.
You can cancel single IPs and subnets on Robot. Please select
Servers from the menu on the left and then select the corresponding server. Under the tab
Cancellation, you can cancel the IPs and/or subnets for the next available date. See also this article about cancellations on Robot.
