How to Assign BYOIP IPs

Validated on 18 Sep 2025 • Last edited on 23 Mar 2026

DigitalOcean Reserved IPs are publicly-accessible static IPv4 and IPv6 addresses. Assign and reassign reserved IP addresses to Droplets as needed, or implement an automated failover mechanism with reserved IPs to build a high availability infrastructure.

Assign a BYOIP IP Address Using Automation

Use the standard reserved IP assign actions to assign BYOIP IP addresses. Substitute a valid address from your prefix for any <reserved-ip> placeholders. The first and second IP address of the BYOIP subnet are reserved.

How to Assign a BYOIP Address Using the DigitalOcean CLI

Install doctl, the official DigitalOcean CLI.
Create a personal access token and save it for use with doctl.
Use the token to grant doctl access to your DigitalOcean account.
```
doctl auth init
```
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 Assign a BYOIP Address Using the DigitalOcean API

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

Using PyDo, the official DigitalOcean API client for 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)

Assign a BYOIP IP Address Using the Control Panel

To assign a BYOIP IP address from the control panel, in the main menu, click Networking, and then click Reserved IPs to see the list of your reserved IPs and BYOIP prefixes.

Find the prefix you’d like to use , and then click Assign to Droplet to open the Assign window.

In the Assign window, type a valid IP address from the prefix, and then select the Droplet to assign it to. The first and second IP address of the BYOIP subnet are reserved.

Afterwards, click Assign IP Address to complete the process.
