How to Reassign or Unassign Reserved IPs

Validated on 15 Nov 2019 • Last edited on 18 Dec 2024

DigitalOcean Reserved IP addresses are a publicly-accessible static IP addresses. Assign and reassign reserved IP addresses to Droplets as needed, or implement a failover mechanism with reserved IPs to build a high availability infrastructure.

You can reassign a reserved IP to point it at a different Droplet. You can also unassign it from a Droplet entirely.

Note
Assigned reserved IP addresses are free, but unassigned reserved IP addresses are not. Learn more about reserved IP pricing.

Reassign a Reserved IP Using Automation

How to Reassign a Reserved IP Using the DigitalOcean CLI

  1. Install doctl, the DigitalOcean command-line tool.

  2. Create a personal access token and save it for use with doctl.

  3. Use the token to grant doctl access to your DigitalOcean account.

              doctl auth init

  4. Finally, run doctl compute reserved-ip-action assign. Basic usage looks like this, but you can read the usage docs for more details:

                doctl compute reserved-ip-action assign <reserved-ip> <droplet-id> [flags]

    The following example assigns the reserved IP address 203.0.113.25 to a Droplet with the ID 386734086:

                  doctl compute reserved-ip-action assign 203.0.113.25 386734086
How to Reassign a Reserved IP Using the DigitalOcean API

  1. Create a personal access token and save it for use with the API.

  2. Send a POST request to https://api.digitalocean.com/v2/reserved_ips/{reserved_ip}/actions

    cURL

    Using cURL:

                    # Assign a Reserved IP to a Droplet
curl -X POST \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
  -d '{"type":"assign","droplet_id":8219222}' \
  "https://api.digitalocean.com/v2/reserved_ips/45.55.96.47/actions"

# Unassign a Reserved IP
# curl -X POST \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
  -d '{"type":"unassign"}' \
  "https://api.digitalocean.com/v2/reserved_ips/45.55.96.47/actions"

    Go

    Using Godo, the official DigitalOcean V2 API client for Go: 

                    import (
    "context"
    "os"

    "github.com/digitalocean/godo"
)

func main() {
    token := os.Getenv("DIGITALOCEAN_TOKEN")

    client := godo.NewFromToken(token)
    ctx := context.TODO()

  // Assign a Reserved IP to a Droplet
    action, _, err := client.ReservedIPActions.Assign(ctx, "45.55.96.47", 8219222)

  // Unassign a Reserved IP
  action, _, err := client.ReservedIPActions.Unassign(ctx, "45.55.96.47")  
}

    Ruby

    Using DropletKit, the official DigitalOcean V2 API client for Ruby: 

                    require 'droplet_kit'
token = ENV['DIGITALOCEAN_TOKEN']
client = DropletKit::Client.new(access_token: token)

# Assign a Reserved IP to a Droplet
client.reserved_ip_actions.assign(ip: '45.55.96.47', droplet_id: 8219222)

# Unassign a Reserved IP
# client.reserved_ip_actions.unassign(ip: '45.55.96.47')

    Python

                    import os
from pydo import Client

client = Client(token=os.environ.get("DIGITALOCEAN_TOKEN"))

req={
  "type": "unassign"
}

resp = client.reserved_ips_actions.post(reserved_ip="49.32.13.21", body=req)

Reassign a Reserved IP Using the Control Panel

To reassign or unassign a reserved IP from the control panel, click Networking in the main menu, then click Reserved IPs.

This page lists your reserved IPs and their assigned Droplets. Open the More menu of the reserved IP you want to reassign or unassign:

Assigned reserved IP with More menu open

From the More menu, click Unassign to unassign the reserved IP entirely, or click Reassign and pick a new Droplet in the Search for a Droplet text box that opens. You can only reassign reserved IPs to Droplets in the same datacenter.
