Overview

Floating IPs provide external access to instances running on private networks. A floating IP maps a publicly routable address to an instance’s private port via NAT on the router. You can associate, disassociate, and reassign floating IPs without downtime.
Prerequisites
  • An active NxtSight account with appropriate permissions
  • Access to the NxtSight Dashboard or CLI configured with credentials
  • API credentials sourced (source openrc.sh)
A router with an external gateway must be connected to the instance’s network before floating IPs can be associated. See Routers.

​
Allocate a Floating IP

2

Configure the allocation

Administrators see an additional Project selector to allocate IPs for other projects. If QoS is enabled on the platform, a QoS Policy selector also appears for all users.
3

Allocate

Click Confirm. The floating IP appears in the list with status Down (not yet associated with an instance).
Floating IP allocated and ready for association.

​
View Floating IPs

Navigate to Network > Floating IPs. The list shows:

​
Associate with an Instance

1

Open the Associate dialog

On the floating IP row, click Associate (available when status is Down or Available).
2

Select the target

Select the instance port to associate with from the fixed IP table. Ports that are not routable to the external network show a reason label.Click Confirm.
The floating IP status changes to Active and shows the associated instance.

​
Disassociate a Floating IP

On the floating IP row, click Disassociate (available when status is Active). Confirm the action. The IP returns to Down status and can be reassigned.

​
Release a Floating IP

Click the More dropdown on the floating IP row and select Release. The IP is returned to the external network pool.
Releasing a floating IP is permanent. If you release a static IP that DNS records or external systems reference, those references will break immediately.
