How to Assign BYOIP IPs

Validated on 18 Sep 2025 • Last edited on 18 Sep 2025

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
  1. Install doctl, the official DigitalOcean CLI.
  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 Assign a BYOIP Address 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.

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.
