DigitalOcean floating IPs are publicly-accessible static IP addresses that you can assign to Droplets and instantly remap between other Droplets in the same datacenter. Implement a failover mechanism with floating IPs to build a high availability infrastructure.
Deleting a floating IP unassigns it and permanently removes it from your account.
To delete a floating IP from the control panel, click Networking in the main navigation, then click the Floating IPs tab. Open the More menu of the floating IP you want to delete, then click Delete.
In the confirmation window, click Delete Floating IP to perform the deletion.
