Floating IPs

Floating IPs are public IP addresses that you can allocate and associate with instances. They provide external connectivity, allowing traffic from the internet to reach your instances inside a VPC.

Command: ace floating-ip Alias: ace fip

Create (Allocate) a Floating IP

Allocate a new floating IP from an external network.

ace fip create --network <external-network-id> [flags]

Flags

Flag	Required	Default	Description
--network	Yes		External network UUID to allocate from
--billing-type	No	hourly	Billing type

Example

ace fip create --network c3d4e5f6-a7b8-9012-cdef-234567890abc

Sample Output

Floating IP allocated.
  ID:              a1b2c3d4-e5f6-7890-abcd-ef1234567890
  IP Address:      45.194.47.108
  Status:          DOWN

A newly allocated floating IP has a status of DOWN until it is associated with an instance.

List Floating IPs

ace fip list

Alias: ace fip ls

Sample Output

ID                                     FLOATING IP        STATUS     FIXED IP           PORT ID
a1b2c3d4-e5f6-7890-abcd-ef1234567890  45.194.47.108      ACTIVE     10.0.0.15          b2c3d4e5f6a7...
b2c3d4e5-f6a7-8901-bcde-f12345678901  45.194.47.109      DOWN       -                  -

JSON Output

ace fip list -o json

Get Floating IP Details

Look up a single floating IP by ID or by IP address.

ace fip get <fip-id|ip-address>

Examples

# By ID
ace fip get a1b2c3d4-e5f6-7890-abcd-ef1234567890

# By IP address
ace fip get 45.194.47.108

Sample Output

  ID:              a1b2c3d4-e5f6-7890-abcd-ef1234567890
  Floating IP:     45.194.47.108
  Status:          ACTIVE
  Fixed IP:        10.0.0.15
  Port ID:         b2c3d4e5-f6a7-8901-bcde-f12345678901
  Instance:        web-server-01
  Created:         2026-05-18T10:30:00Z

Associate a Floating IP

Associate a floating IP with an instance to make the instance reachable from the internet.

ace fip associate --ip <floating-ip-address> --instance <instance-id> [flags]

Flags

Flag	Required	Description
--ip	Yes	Floating IP address (e.g. 45.194.47.108)
--instance	Yes	Instance UUID to associate with
--fixed-ip	No	Fixed IP address (if instance has multiple NICs)

Examples

Basic association:

ace fip associate --ip 45.194.47.108 --instance a1b2c3d4-e5f6-7890-abcd-ef1234567890

With a specific fixed IP (multi-NIC instance):

ace fip associate --ip 45.194.47.108 \
  --instance a1b2c3d4-e5f6-7890-abcd-ef1234567890 \
  --fixed-ip 10.0.0.15

Sample Output

Floating IP 45.194.47.108 associated with instance a1b2c3d4-e5f6-7890-abcd-ef1234567890.

---

Disassociate a Floating IP

Remove the association between a floating IP and an instance. The floating IP is retained in your account but no longer routes traffic to the instance.

ace fip disassociate --ip <floating-ip-address> --instance <instance-id>

Flags

Flag	Required	Description
--ip	Yes	Floating IP address
--instance	Yes	Instance UUID to disassociate from

Example

ace fip disassociate --ip 45.194.47.108 --instance a1b2c3d4-e5f6-7890-abcd-ef1234567890

Sample Output

Floating IP 45.194.47.108 disassociated from instance a1b2c3d4-e5f6-7890-abcd-ef1234567890.

---

Delete (Release) Floating IPs

Release one or more floating IPs back to the pool.

ace fip delete <fip-id> [fip-id...]

Alias: ace fip rm

Disassociate a floating IP from its instance before deleting it. Deleting a floating IP releases the address permanently -- you cannot reclaim the same IP.

Example

# Release a single floating IP
ace fip delete a1b2c3d4-e5f6-7890-abcd-ef1234567890

# Release multiple floating IPs
ace fip delete <fip-id-1> <fip-id-2>

Sample Output

Released 1 floating IP(s).

Common Patterns

Expose a Web Server

# 1. Allocate a floating IP
ace fip create --network <external-network-id>

# 2. Associate it with your instance
ace fip associate --ip 45.194.47.108 --instance <instance-id>

# 3. Ensure the security group allows HTTP/HTTPS
ace sg rule-add --sg <sg-id> --protocol http
ace sg rule-add --sg <sg-id> --protocol https

Move a Floating IP Between Instances

# Disassociate from the old instance
ace fip disassociate --ip 45.194.47.108 --instance <old-instance-id>

# Associate with the new instance
ace fip associate --ip 45.194.47.108 --instance <new-instance-id>
