A DigitalOcean Floating IP is a publicly-accessible static IP address that you can assign to a Droplet. It provides an additional static address you can use to access a Droplet without replacing or changing the Droplet’s original public IP.
You can instantly remap Floating IPs from one Droplet to another in the same datacenter. This functionality is available via both the DigitalOcean Control Panel and the DigitalOcean API. You can use the API for automatic reassignment, like a failover mechanism as part of a high availability server infrastructure.
