Floating IPs

A Floating IP is a portable public IP address owned by your organization. You can assign it to one machine, then move it to another at any time without changing the address. Manage them on the Floating IPs page in my.cubepath.com.

What it's for

Because the IP belongs to your organization and not to a single machine, it keeps the same address across rebuilds and migrations. That makes it ideal for stable DNS records, failover, and moving a workload to a new server without updating anything that points at the old address.

Note: A Floating IP only attaches to machines in the same location. An IP acquired in one region can't be assigned to a server in another.

Acquire an IP

Click Acquire IP, choose the Type (IPv4) and the Location, then confirm. The new address appears under the Single IPs tab. Larger allocations are grouped as Subnets, where you can expand a range to see and manage every individual IP it contains.

Assign and unassign

The Assigned To field shows the VM or dedicated server an IP is currently attached to, or Unassigned if it's free. Move or detach an IP to point it at a different machine.

Note: A server reboot applies the change on the machine.

Reverse DNS (rDNS)

For an assigned IP, use the edit control next to Reverse DNS to set its PTR record (for example mail.example.com). Leave it empty to remove the record. This is useful for mail servers and any service that expects a valid reverse lookup.

Release an IP

Use the delete action on a secondary IP to release it back. The address returns to the available pool and stops billing.
